Re: Sort the array

First, code tags are <code> and </code> not [code] and [/code].

For a numerical sort you want to use a numerical comparison operator, for example:

my @theList = ( 205, 4, 100, 1, 2, 2000, 6, 93, 2, 65 );
my @theSortedList = sort { $a <=> $b } @theList;
print join( ',', @theSortedList ), "\n";

Hi, your solution works fine. But Can you explain the line a but more , `my @theSortedList = sort { $a <=> $b } @theList;` [download] Since i m new to Perl, i did not understood what its actually doing. Thanks, Shekar	[reply] [d/l]

`<=>` is a numeric equality operator. See perlop for details. `$main::a` and `$main::b` are special variables that sort uses internally. So the code block is a call-back subroutine that sort uses to compare the values of the incoming list.	[reply] [d/l] [select]
