Here is my implementation
I thought of the same thing but did not do that during the contest and it's complexity is O(N*N*k),I wonder how did it pass the test cases? Correct me if I am wrong.
The judge data was pretty weak you see, many people solved it with O(k*n^2) solutions with a few optimizations. I would really like to know how to solve it in a better complexity.
