CodeForce - GitHub Pages So, I want to propose my own solution for problem A: As stated in the answer by Mike Mirzayanov, in order to get the difference between the number m and the nearest round number < m, we need to compose that round number. I think you start with a larger number, because in the worst case that you divide it, you could still use it for smaller numbers. My basic idea was to reduce every number in array A and B to their largest odd factors (by dividing them 2 as long as possible) and store the values in two different multisets.
