Hi,
Hello,
I have an array which has few elements like '1,2,3,4,2,3,1,2,1,1,1,4,6,7'
i need to know how many times each element has occurred in the same array.
for example 1-5 times
2-3 times...
Use a hash.
#!/usr/bin/perl
use strict;
use warnings;
my @array = (1, 1, 2, 4, 2, 1, 9, 42, 0, 0, 0, 1, 0, 0, 2);
my %count;
$count{$_}++ for @array;
for my $c( sort{ $b <=> $a } keys(%count) ) {
printf("% 3d appeared %d times\n", $c, $count{$c});
}
Output:
42 appeared 1 times
9 appeared 1 times
4 appeared 1 times
2 appeared 3 times
1 appeared 4 times
0 appeared 5 times
