Find RANGE of Data

Question

Hi,
I have data for which i need to prepare range script.
Sample data is
col1
1
11
2
3
B
C
B12
c1
C123
c2
c3
I need to prepare a script to dispaly the data in the following manner
val('1','3'); -- since 1,2,3 are in range so 1 to 3
val('11'); -- since 11 is not in range of any column
val('B','C'); -- since B,C are in range so B to C
val('B12'); -- since B12 is not in any range
val('c1','c3');
val('C123');
where val , ( , ) are strings which can be concatenated to the data.
I tried converting to ascii and sort it but it doesnt help since some has same starting characters.
Quick help is appreciated. Also let me know if it can be acheivable.
Thanks
