I do such things as follows:

   ans1 = ans2 = nil
   ans1, ans2 = $1.to_i, $2.to_i if STDIN.gets =~ /(\d+)\s+(\d+)/
   invalid_input if not ans1 or not ans2
   
or

   if STDIN.gets =~ /(\d+)\s+(\d+)/
      ans1, ans2 = $1.to_i, $2.to_i
   else
      invalid_input
   end

The first example has the advantage, that ans1 and ans2 are already
initialized.
