The main thing about the problems in CP is that problems are framed in such a way that the ones who have good knowledge of the constraints, parameters, time complexity, effective use of data structures will be able to the problems. So, even though if you do know the algorithm, its hard. As we all know CP is basically math and combinations of the logic part. So, here there are some of the codes for problems of math and logic part in two diffrent folders.
