Count Pairs in Two Arrays

Explore how to count pairs of indices in two arrays where the sum of elements from the first array is greater than from the second. Understand the problem constraints and apply sorting and search methods such as two-pointer techniques to efficiently solve this common coding interview challenge.

We'll cover the following...

Statement

You are given two positive integer arrays, nums1 and nums2, both of length nn. Your task is to count and return the number of pairs of indexes (i,j)(i, j) where:

  • i<ji < j ...
