Convert json files
The json files inside the IPARC_ChallengeV2 repository has a slightly different format than the typical ARC files.
This script takes the the IPARC_ChallengeV2/Dataset dir as dir named input.
Then run python a.py. It flattens the nested directory structure.
Then run python b.py. It takes the last input/output pair and turns it into a test pair.
Now the output_b dir contains the converted dataset.
