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
