// This program should scan in a target word and a guess, then print the
// Wordle-style feedback for that guess:
//   'G' - the letter is correct and in the correct position
//   'Y' - the letter is in the word, but in the wrong position
//   '.' - the letter is not in the word
//
// Unfortunately, this code contains a number of errors.
// It's your job to fix them, good luck!
