Question

Write a C++ code for the given problem: 

Given two arrays X and Y of positive integers, find the number of pairs such that xy > yx (raised to power of) where x is an element from X and y is an element from Y.

Input: 

M = 4, X[] = [2 3 4 5]

N = 3, Y[] = [1 2 3]

Output: 5

Explanation: 

The pairs for the given input are 

21 > 12 , 31 > 13 , 32 > 23 , 41 > 14 , 

51 > 15 .

Expected Time Complexity: O((N + M)log(N))

Constraints:

1 ≤ M, N ≤ 105

1 ≤ X[i], Y[i] ≤ 103
