I completed pset1 but I seem to have some problem running the Check50. when I put my output next to the one provided for testing, it seems the exact same... I tried to use an array with chars, is it ok to represent the gap and "air" with spaces? or some other output is expected? Thank you What I get from the Check50 Comparison between given program output and my own

  • kareem or @curiouskiwi should be able to confirm this, but I was under the impression that check50 isn't set up to test the hacker editions.
