Problem description Rudreshwar likes random numbers and random arrays. Today Rudreshwar started playing with a couple of Arrays A and B, each of size N. Initially A is filled with zeros. Rudreshwar filled B with random numbers. Rudreshwar visits each index i (1 i N) in random order. When at i, he selects another random index j such that j is greater or equal to i. He then increments A[i], A[i+1
