These are my solutions in C and Python, not necessarily the best solutions. I've solved most of the first 100 problems, currently working on cleaning the code and uploading it. I will try to solve more problems in the future.

Notes

Solutions for problems 82, 86, 95, and 145 in Python are quite slow.
Solutions for problems 84, 89, 96, 97. 99, 102, 112, 124 and 357 have been implemented in C but not in Python.
Solutions for problems 88, 90 and 91 have been implemented in Python but not in C.
