Steven Truong struong@berkeley.edu The set_challenge.py file holds the main class that computes our desired output and it depends on utils.py. A brief test function is used in test_set.py and requires: input/1 input/2 input/3 input/4 Otherwise, comment out lines 10-37. test_set.py is ran with an input file in the format of the input in the instructions and writes to an output file 'output/_out' in the format specified in the instructions. I've also assumed per the instructions that inputs will be given in a valid form. # python test_set.py <input_file> output file after running the command above = output/_out
