Hello,

I need some suggestion regarding sorting an array.

Ex:


@arr=(100,20,3,45,1);
#To sort the above array I did
@index=sort{ $arr2[$a] <=> $arr2[$b] } 0 .. $#arr;
print @index;

Output:

4 2 1 3 0

[download]

But, if I have an array like the following

@arr=((ch1,100), (ch2,20), (ch1,13), (ch2,45), (ch1,1));

How to sort this kind of array (first sort first element and then sort by second element)

Sample output should be,

4 0 2 1 3

Any suggestions, please advise.

Thanks,
