in reply to Challenge - Creative Way To Detect Alpha Characters
It would be hard to suggest a solution w/o knowing the capabilities of that language. Does it support index() like function? Can it convert between hex and decimal values? OTOH, would a solution in perl do?
UPDATE: I decided to give a perl solution anyway. Use index() in a loop (similar to CombatSquirrel's reply and possibly slower) ...
sub has_alpha { my $string = shift; return scalar map { index($string , $_) == -1 ? () : 1 } ('a' .. 'z' , 'A' .. 'Z') ; }
