Recursion with array

hi
i got this question , int values[] int index int amount i need to check if there is sum of elementv in values that equal to amount
example
values[]={5,22,13,5,7,-4}
amount=31
22+13+(-4)=31
return true
the signature fo function call in recursion is:
cover (int[] values,int i,int amount)

henvertis, you hijack someone else's thread to post your "question". I suggest you to create a thread of your own and tell you that it might be a good idea to post the code you're working on because just posting a description of the problem might result into other forum members assuming you just want someone to do it for you (some call this cheating).
You then create a new thread, but (again) just with the problem description. I respond to that thread but you never got back to me, and now you're back again with another new thread and again just the problem description!
What's wrong with you?

Recursion with arrays

Hi,
I am having trouble with creating a recursive method to sum all
elements in an array. I am new to recursion and am getting
confused.
Here is a method I am working with:
I am trying to sum all the sides of a triangle whose sides
are stored in the array sides [ ], but can't seem to add
more than the sides[2] and sides[1] elements.
Any ideas? One of the requirements is that 0<= index < size or array.
Thanks,
int perimeter() {
return perim(0);
int perim(int index) {
if (index == sides.length-1)
return sides[index];
else{
int sidesTotal = perim(index+1);
return sidesTotal + sides[index-1];
}

> I am having trouble with creating a recursive method
to sum all elements in an array.
class ReallyBadUseOfRecursionDemo {
    public static int recursiveSum(int[] array) {
        if (array == null || array.length == 0) return 0;
        if (array.length == 1) return array[0];
        return array[0] + recursiveSum(java.util.Arrays.copyOfRange(array, 1, array.length));
    public static void main(String[] args) {
        assert 0 == recursiveSum(null);
        assert 0 == recursiveSum(new int[0]);
        assert 42 == recursiveSum(new int[] { 42 });
        assert 6 == recursiveSum(new int[] { 1, 2, 3 });

Recursive MISO (Array)

Hello. I have problem with recursive MISO Array. Stimulus is 2D array and response is 1D array. This arrays are same lenght.After run write error 20 002. I don't know where is a problem. Please help me. Thanks

Hey Mizda,
Your B matrix and Delay matrix were incorrect.
The B matrix should be scalar, and Delay matrix should be initialized (it can be 'zero', but it can't be empty).
Please, check this simple example!
Best regards,
Matyas

Hi,
I have a MBP 13' Late 2011 and Yosemite 10.10.2 (14C1514).
Until yesterday, I was using Garmin ConnectIQ SDK and all was working fine.
Yesterday, I've updated my system with latest security updates and Xcode updates too (Version 6.2 (6C131e)).
Since, I can't launch the ConnectIQ simulator app, I have this message in console :

I tried some stuff with plutil

I also try to download a fresh version of the connectIQ SDK and no changes.
Any idea ?

What are right parameter types of ODCIIndexInsert in case of creating indextype WITH ARRAY DML option (documentation mismatch)

Hello.
During developing Domain Index for Oracle 11.2.0.1.0 (problem also appears in 12с) i was faced with misunderstanding of parameter types of function
ODCIIndexInsert in case of creating indextype WITH ARRAY DML option
According to Oracle documentation
http://docs.oracle.com/cd/E11882_01/appdev.112/e10765/ext_idx_ref.htm#i76892
In case of WITH ARRAY DML option Oracle will invoke ODCIIndexInsert with following signature
FUNCTION ODCIIndexInsert(
ia ODCIIndexInfo,
ridlist ODCIRidList,
newvallist varray_of_column_type,
env ODCIEnv)
RETURN NUMBER
In my case indexed column has datatype NUMBER so i defined varray_of_column_type as SYS.ODCINumberList
STATIC FUNCTION ODCIIndexInsert(ia in sys.ODCIIndexInfo, ridlist in sys.ODCIRidList, newvallist in sys.ODCINumberList, env in SYS.ODCIEnv) RETURN NUMBER
Indextype was created as
CREATE INDEXTYPE test_index_type
FOR
test_eq(number, number)
USING index_methods
WITH ARRAY DML(number, sys.ODCINumberList)
WITH LOCAL RANGE PARTITION
WITH SYSTEM MANAGED STORAGE TABLES;
or
CREATE INDEXTYPE test_index_type
FOR
test_eq(number, number)
USING index_methods
WITH ARRAY DML
WITH LOCAL RANGE PARTITION
WITH SYSTEM MANAGED STORAGE TABLES;
(problem occurs in all cases)
CREATE TABLE test_table (id NUMBER (19,0));
CREATE INDEX test_index ON test_table(id) INDEXTYPE IS test_index_type;
When attempting to insert data in the table
insert into test_table values (1);
oracle raise exception
Error starting at line 53 in command:
insert into test_table values (1)
Error at Command Line:53 Column:1
Error report:
SQL Error: ORA-29925: cannot execute SCOTT.INDEX_METHODS.ODCIINDEXINSERT
ORA-06553: PLS-306: wrong number or types of arguments in call to 'ODCIINDEXINSERT'
ORA-06553: PLS-306: wrong number or types of arguments in call to 'ODCIINDEXINSERT'
29925. 00000 - "cannot execute %s"
*Cause:    The specified function does not exist or does not have an
           appropriate signature.
*Action:   Implement the function with the appropriate signature.
So my question is.
Is it normal behavior of oracle (according to documentation)?
What is correct signature of ODCIIndexInsert function in case of INDEXTYPE creation with 'WITH ARRAY DML' option and fact that indexed column has NUMBER datatype?
By the way if i define indextype without 'WITH ARRAY DML' option signature is clear, and working. But this approach doesn't satisfies our performance needs.
Also if i define index type with option 'WITH ARRAY DML WITHOUT COLUMN DATA' and use signature
static function ODCIIndexInsert(ia sys.odciindexinfo,   ridlist sys.odciridlist, env sys.ODCIEnv) return number
Everything works too. But this approach doesn't satisfies our business needs.
Is it a way to define ODCIIndexInsert parameter types (in case of indexing number column) so that batch inserting works according to documentation ?
FUNCTION ODCIIndexInsert(
      ia ODCIIndexInfo,
      ridlist ODCIRidList,

Trouble with arrays

Hi!
I have to write a program where you enter a name of a person and his points in a game using arrays. The program stops when you enter -99
Then the output should be like this
Person 1 45
Person 2 89
Person 30 X
We have just begun with arrays and i am not so good at it, i don't know what to enter in the brackets []. Can somebody help me? It has a lot of errors
Here is my program:
public class GradeArray {
     public static void main(String args[]) {
     String NameArray[] = new String [ 30 ];
     String NumberString;
     int NumberArray[] = new int [ 30 ];
     int ControlExit = 0;
     String output = "Name\t\tPoints\n";
     while (ControlExit == 0) { // start while
     NameArray[] = JOptionPane.showInputDialog(
null, "Enter the name of the person");
     NumberString = JOptionPane.showInputDialog(
     null, "Enter "+NameArray[]+"'s points(0-100) Enter -99 toExit");
     NumberArray[] = Integer.parseInt(NumberString);
     if (NumberArray[] == -99)
     ControlExit = 1;
     } // end while
     for (int Control = 1; Control <= NumberArray.length; Control++)
     output += NameArray[] + "\t\t" + NumberArray[] + "\n";
          JTextArea outputArea = new JTextArea();
          outputArea.setText( output );
JOptionPane.showMessageDialog(null,
outputArea);
System.exit( 0 );

ok, i understand it better but my modified program has still errors
import javax.swing.*;
public class GradeArray2 {
public static void main(String args[]) {
String NameArray[] = new String [ 30 ];
String NumberString;
int Number;
int NumberArray[] = new int [ 30 ];
int ControlExit = 0;
String output = "Name\t\tGrade\n";
while (ControlExit == 0) { // start while
Name = JOptionPane.showInputDialog(
null, "Enter the name of the person");
Name = NameArray[Name];
NumberString = JOptionPane.showInputDialog(
null, "Enter "+NameArray+"'s points(0-100) Enter -99 to Exit");
Number = Integer.parseInt(NumberString);
NumberArray[Number] = Number;
if (NumberArray[Number] == -99)
ControlExit = 1;
} // end while
for (int Control = 1; Control <= NumberArray.length; Control++)
output += NameArray[Name] + "\t\t" + NumberArray[Number] + "\n";
JTextArea outputArea = new JTextArea();
outputArea.setText( output );
JOptionPane.showMessageDialog(null,
outputArea);
System.exit( 0 );

Hey guys, I'm a beginner programmer and I'm having a bit of a tough time with arrays. I could really use some help!
What I'm trying to do is roll one die and then record the rolls.
Here is my sample I/O:
How many times should I roll a die?
-> 8
rolling 8 times
2, 1, 5, 6, 2, 3, 6, 5
number of 1's: 1
number of 2's: 2
and so on....
Here is my incomplete code at this moment:
//CountDieFaces.java
import java.util.Scanner;
import java.io.*;
import library.Gamble;
public class CountDieFaces
    //prompt for and read in: number of times user wants to roll one die
    //simulate rolling a die that many times, counting how many times each face 1 thru 6 comes up
    //print out: each roll
    //AND the total number of times each face occured and the percentage of the time each face occured.
    Scanner scan = new Scanner(System.in);
    int[] faceCount= {0,0,0,0,0,0,0};
    int dice;
    System.out.println("How many times would you like to roll the die?");
    int dieCount = scan.nextInt();
    int dieRoll = Gamble.rollDie(); // Main calling class method
    int count = 1;
    while(count < dieCount)
        System.out.println(faceCount[count]);
        count++;
}Here is the gamble library:
//Gamble.java
package library;
public class Gamble
     // returns 1, 2, 3, 4, 5, or 6
     public static int rollDie()
          int dieRoll = (int)(Math.random()*6)+1;
          return dieRoll;
}and here are the errors I have so far:
----jGRASP exec: javac -g CountDieFaces.java
CountDieFaces.java:19: <identifier> expected
     System.out.println("How many times would you like to roll the die?");

          ^
CountDieFaces.java:27: ')' expected
          System.out.println(faceCount[count]);
I'm really confused with how a the gamble library gets put into the array, so any help is appreciated! Also if anyone could explain the errors to me, I would really appreciate it.
thanks in advance,

D'oh!
Thanks you guys, fixed that. Although I'm having trouble with storing the die roll in the array. Any suggestions?

ADF Mobile: WebService data control method call with array

JDev 11.1.2.3
ADF Mobile deployed to Android emulator
Hello All,
I am trying to invoke a method in my Web Service data control and get the following exception
Caused by: ERROR [oracle.adfmf.framework.exception.AdfInvocationRuntimeException] - Cannot serialize: [I@1dbae822
        at oracle.adfmf.dc.ws.soap.SoapTransportLayer.invokeSoapRequest(Lorg/ksoap2/SoapEnvelope;)Ljava/lang/Object;(Unknown Source)

            <element maxOccurs="unbounded" minOccurs="0" name="taskID" type="decimal"/>
     </sequence>
   </complexType>
</element>For the input to my binding, I have tried int[], Integer[] and List<Integer>. All of these result in similar errors.
I have also tried invoking this through a regular ADF application and that works fine with an int[]. It looks like something specific to the ADF Mobile SOAP layer.
Is this a bug or a restriction in the framework? Any workarounds that has worked for anyone?

No luck. A WS DC method call with a simple parameter (java.lang.String or java.lang.Integer) works fine but I can't get it to work when there is an array input.
I have tried WS methods with int arrays and simple string arrays without any luck. All of them result in a cannot serialize error.
I can't figure out what I am doing wrong. Are there any working WS Datacontrol samples with array inputs?

How to do like this with array?

How to do like this with array?
I have 2 constants array put in main while loop ( array1{6,6}; array2{4,4} ). Those arrays will be come the input data for st in the small while loop inside.
The input data look like : [6,6],[4,4],[6,6],[4,4]...... I have to put input data to result array[8]. The method is:
input data result data
[6,6] --------------------------------------------> [6,6,0,0,0,0,0,0]
[4,4] --------------------------------------------> [6,6,4,4,0,0,0,0] ( this period, just add each element in new array)
[6,6] --------------------------------------------> [6,6,4,4,6,6,0,0]
[4,4] --------------------------------------------> [6,6,4,4,6,6,4,4]
[6,6,4,4,6,6,4,4] ( 1st period )
When the las index of result data array is filled in, I have to collapse the result data array to be this array:
----------> collapse: [6,4,6,4,0,0,0,0] ( take the average of 2 continuous element add to new result data array)
Next input data
[6,6] --------------------------------------------> [6,4,6,4,6,0,0,0]
[4,4] --------------------------------------------> [6,4,6,4,6,4,0,0] ( this period, add the average of 2 continuous elements in new array )
[6,6] --------------------------------------------> [6,4,6,4,6,4,6,0]
[4,4] --------------------------------------------> [6,4,6,4,6,4,6,4]
[6,4,6,4,6,4,6,4] ( 2 nd period)
----------> 2nd collapse [5,5,5,5,0,0,0,0] ( take the average of 2 continous element add to new result data array)
Next input data
[6,6] ....wait until input data has 4 elements
[4,4] -------------------------------------------------------------------------------------> [5,5,5,5,5,0,0,0]
[6,6] ....wait until input data has 4 elements
[4,4] -------------------------------------------------------------------------------------> [5,5,5,5,5,5,0,0]
[6,6] ....wait until input data has 4 elements
[4,4] -------------------------------------------------------------------------------------> [5,5,5,5,5,5,5,0]
[6,6] ....wait until input data has 4 elements
[4,4] -------------------------------------------------------------------------------------> [5,5,5,5,5,5,5,5]
[5,5,5,5,5,5,5,5] ( third period )
----------> 3rd collapse [5,5,5,5,0,0,0,0]
This wayl to make the tren graph.I made an VI to do that , but it's not yet correct.

Frankly, I don't understand your problem description or your VI.
In the description, the output array has a fixed size of 8 elements, is this correct? In this case you should initialize an array of 8 elements and do all operations "in place". I don't udnerstand the purpose of all the other code.
There are a lof of things that don't make any sense at all.
The second largest loop has no purpose, because it iterates only once per call
Sometimes you are concatenating an empty array to an existing array. This makes no difference.
Why is some of your data EXT representation???
What's up with complicated constructs such as that small loop shown in the picture. I show a somewhat simpler alternative.
Anyway, I have a hard time understanding your description. What should happen at the end? Do you have a link to a website that describes the algorithm? Does the algorithm have a name?

Problem is detected with Array : 01

I was backing up my server when it suddenly turned off. When it restarted it showed a critical error message saying "Problem is detected with Array : 01".
Windows tried starting and kept rebooting so I just turned it off.
When I launch the RAID utility I clearly see that the drive 02:01 seems ok but the other one is marked as "failed orisconnected" (it is connected ans spinning).
This is the spec: On the server I have windows 2012R2 installed on two HD 1TB on RAID1.
I habe an unused NAS, so I decided to create an iSCSI drive as a Target, and run the windows backup utility to do a Full Backup on it.hat may I have done wrong and how could I resolve this issue?
This clearly is related to the windows backup utility since this server was working fine until then.
Thanks.

Hi,
The issue could be due to that one of the two drive is failed in the RAID 1. You need to replace the failed drive and rebuild the array automatically.
Best Regards,
Mandy

Simple question with arrays

Im a couple days new in java, Ive been searching for an answer for hours and havent found a solution.
This is the mistake it shows (when trying to use any element of the array):
array required, but java.util.ArrayList <java.lang.String> found
The array is:
public static ArrayList<String> numList = new ArrayList<String>();
Im filling it this way: (so that it contains each word of a file in separate)
BufferedReader br = new BufferedReader(new FileReader("Archivo.txt"));
try
while(true)
String aLine = br.readLine();
if(aLine == null) throw new EOFException("Le?do todo el archivo.");
if(!aLine.equals(""))
StringTokenizer st = new StringTokenizer(aLine);
while(st.hasMoreTokens())
numList.add(st.nextToken());
}catch(EOFException e)
The problem comes when I try to use the elements of the array (in specific when trying to convert each element of the array to int, so that i can do math operations with them).
for example:
for (a=0; w>a; a++)
int x = Integer.parseInt(numList[a])
Can anyone help me with this? (where is the mistake and how to convert from string array elements to int)
Thank you // Muchas Gracias

The trouble is that you're confusing ArrayLists with arrays. They're not the same thing.
Currently you're making an ArrayList. If you want an array of String, do this:
String[] myArray = new String[50];
int i = 0;
while(st.hasMoreTokens()) {
myArray[i] = st.nextToken();
i++;
}Or perhaps better yet:
String[] numListArray = numList.toArray(new String[0]);But you really don't need an array for what you're doing. Use an Iterator.
Iterator<String> strings = numList.iterator();
while(strings.hasNext()) {
int x = Integer.parseInt(strings.next());
}You get the idea. Read the Collections tutorial about iterators. Read the language spec about arrays. Also look at the java.util.Arrays class.

Recursive WITH (Recursive Subquery Factoring) Never Returns

11.2.0.2 database on Windows, SQL Developer Version 3.2.20.09, build MAIN-09.87 (Database and SQL Developer are on the same machine. I have also tried connecting to a Linux 11.2 database and have the same results.)
I've been doing some simple testing with recursive WITH (Recursive Subquery Factoring) and when I run this following statement in SQL*Plus it returns instantly. However when running in SQL Developer it never returns, I've let it run for quite a long time (172 seconds) and gotten nothing, I finally kill the statement. Once I ran it and even killing the job didn't come back. I can get an explain plan but if I try to run it, run as script or autotrace it never returns. I have only one plan in the plan_table for this test, and it's only 4 lines long. No errors, no messages.
WITH get_plan (query_plan, id, planlevel) as
select ' '||operation||' '||options||' '||object_name query_plan, id, 1 planlevel
from plan_table
where id = 0
union all
select lpad(' ',2*planlevel)||p.operation||' '||p.options||' '||p.object_name query_plan, p.id, planlevel+1
from get_plan g, plan_table p
where g.id = p.parent_id
SELECT QUERY_PLAN FROM GET_PLAN ORDER BY PLANLEVEL;

Hi Jeff, using either give the same results. The query is "running", as is the little graphic with the bouncing gray bar is moving back and forth saying either "Query Results" or "Scriptrunner Task" as appropriate.
OK this is odd. I run a count(*) on plan_table in SQL*Plus and get 4, in SQL Developer I get 487. Hun? That makes no sense I'm connect as the same user in each. Where are all these other entries coming from and why can't I see them in SQL Plus? Does SQL Developer have it's own PLAN_TABLE?
**EDIT --- Yes that seems to be the case. The PLAN_ID I see in SQL Plus doesn't even exist in the SQL Deveropler version of the table. OK that's good to know. I assume the plan_table for SQL Developer is local to it somehow? It's not in the database as best I can see.

To use "analytic function" at "recursive with clause"

http://docs.oracle.com/cd/E11882_01/server.112/e26088/statements_10002.htm#i2077142
The recursive member cannot contain any of the following elements:
・An aggregate function. However, analytic functions are permitted in the select list.
OK I will use analytic function at The recursive member :-)

Let us discussion "non recursive with clause" usage

I think there are 3 "non recursive with clause" usage.
My question is do you know more "non recursive with clause" usage ?

Another option is to use it to materialize remote data on the fly. Especially in combination with the materialize hint.
I think I used this tecnique once, but can't find the proper example anymore. Very simplified it could looked like this:
with fetchData as (Select /*+materialize */ * from myremoteTable@databaselink where status = 'CURRENT')
select *
from fetchdata r
full outer join localData l on r.id = r.id
where l.status = 'CURRENT'
;From 11g onwards: use the with clause to create better column names in larger select from dual combinations.
Not sure with that results in a suitable use case.
So instead of
with orders as
(select 1 id , 173 order#, 'John' customer, 'America' region from dual union all
select 2 id , 170 order#, 'Paul' customer, 'UK' region from dual union all
select 3 id , 240 order#, 'Hans' customer, 'Europe' region from dual union all
select 4 id , 241 order#, 'Francois' customer, 'Europe' region from dual )
select * from orders;you can now write
with
orders (id, order#, customer,region) as
(select 1 , 173 , 'John' , 'America' from dual union all
select 2 , 170 , 'Paul' , 'UK' from dual union all
select 3 , 240 , 'Hans' , 'Europe' from dual union all
select 4 , 241 , 'Francois' , 'Europe' from dual )
select * from orders;THis makes it a little easier to create tase data useing some excel sheet I guess.
