CodeChefOpen on judge ↗

You have two arrays A and B, each containing N integers. Elements of array B cannot be modified. You may perform an arbitrary number of operations (including zero number of operations). In one operation, you can choose one index i (1 ≤ i ≤ N) and increment Ai by 1. Each index can be chosen any number of times. Find the minimum number of operations required to modify the array A such that for ev
