I've encounterd a problem when comparing the near match, in a single "for loop" I can only compare the numbers of the same position in the 4-digit number, this makes the comparison impossible.
The good news is that I finally finish the exact match part, that's really a piece of cake with the help of the fake array.
Do I need to use "looping the loop" or 2 "for loop" to write it or anything else?
