Sorting an array

[mns9939]

Hi,

I have a hash array with key-value pair like
1-AAAA
2-BBBB
.
.
.
11-KKKKK
....
..
21-LLLL

however, when i loop through the array, it does not print the values in the order it was put in.
How do i make it to print the values in the order in was put in?

Thanks for your help,
Madhu

The easiest way to print the keys or values in order is to sort them like:

@sortedkeys = sort(keys %hash);
@sortedvalues = sort(values %hash);

So if you want to print the key-value pair sorted on keys.

foreach $key (@sortedkeys) {
    print "key=$key value=$hash{$key} \n";
}

this is a numerical sort
@sorted = sort { ( $a ) <=> ( $b ) } @unsorted;


this is a alphabetical sort
@sorted = sort { lc( $a ) cmp lc( $b ) } @unsorted;


hope this helps ya
