Another solution for the hell of it. No idea how you would coax the second solution out of it. No matter how I tweak things (shotgun debugging :) it converges to the same answer. Hmm.

#!/usr/bin/perl use strict; use warnings; my @arr = (0..9); my %hash; @hash{@arr} = (0) x @arr; sub scanit { my $number = shift; my $cnt = 0; for (0..9) { foreach my $c (split //, $hash{$_}) { $cnt++ if ($number == $c); } } $cnt+1; } my $solcount=0; while (1) { my $cond = 0; # update the counts for (my $i=9; $i>=0; $i--) { my $cnt = scanit($i); $hash{$i} = $cnt; } # check whether our solution is valid. for (0..9) { my $cnt = scanit($_); $cond = 1 if ($hash{$_} != $cnt); } # print it if it is. if ($cond == 0) { my @print; for (1..9) { push @print, "of $_ "."s is $hash{$_}"; } print "The number of 0s in this sentence is $hash{0}, " . join(", ", @print) . "\n"; die; } else { $cond = 1; } }
