Ladder Name: 9 - Codeforces Div. 1, D

Description: List of random Codeforces problems, all of them are Div. 1 D problems. The problems are sorted, the most solved problem comes first. This is a good practice for whoever can solve almost all Div. 1 A, B and C problems, but might have some difficulties while solving the C problems.
