Look again, and the index value for 2 is 27.

Well, I had just created some print statements to track the words... I've since deleted that but you can easily do the same. Also: I did notice that your code fails on other types of test, so give it a thorough look while print/debugging. Best of luck!

You have to check '(' and ')' but you can ignore those : {} []

Hi junioryao, I have run your code and checked its output. It returned 1 (claiming Bob had won) on a random test wherein neither player could find any match word for the original game word. Tests of this type should return -1.
