I have tried for hours to solve this. Ok, the user enters a number, say 2020. 2020 is put into an array. {2, 0, 2, 0}. At @array[0] = 2; 0 occurs twice in the string so this should print true; @array1 1 occurs 0 times in the string so this should return true too. and @array[2] 2 occurs 2 times in the string and this returns true; But when I enter 2020 , I get false true false true. I've looked at this for hours.
#!/usr/bin/perl -w print "Enter number : "; my $num = <STDIN>; chomp($num); @nums = split /(?<=[\d])/, $num; $i = 0; foreach (@nums) { if ($num =~ /[$i]{$_}/) { print "true" } else { print "false"; } $i++; }
