This is throwing the entire long string into the switch. I think you’ll want to use a switch for each letter in the string instead.

This checks if str is strictly equal to 0, which will never happen. Same with all the other cases.

  • pair is not defined
  • I suppose you wanted to put those two values in an array a la ["A", "T"] but forgot the brackets?
