in reply to boolean calculation with very large data

#!/usr/bin/perl -l my $region1=[[1,2],[5,7]]; my $region2=[[2,6]]; sub max { return $_[0] > $_[1] ? $_[0] : $_[1]; } sub min { return $_[0] < $_[1] ? $_[0] : $_[1]; } sub getIntersect { my ($reg1, $reg2) = @_; return if $reg1->[1] < $reg2->[0]; return if $reg1->[0] > $reg2->[1]; return (max($reg1->[0], $reg2->[0]), min($reg1->[1], $reg2->[1])); } foreach my $r1 (@$region1) { foreach my $r2 (@$region2) { if( my @is = getIntersect($r1, $r2) ) { print "[$is[0], $is[1]]"; } } }
