in reply to Deleting elements from array questions

the subject of "deleting elements from array questions" comes up pretty often, so i decided to write a subroutine that would handle the job once and for all. note that it will only remove elements from array questions, not array statements or other types of questions.
$ques = "how do i make an array spin around?"; $element = 4; print delete_element($element, $ques), "\n"; sub delete_element { my ($element, $question) = @_; if($question =~ /array.*\?$/i) { @elements = split(' ', $question); $elements[$element] = ''; return join(' ', @elements); } else { print "That is not an array question!\n"; return $question; } } output: how do i make array spin around?
