Number of Pairs Satisfying Inequality

You are given two 0-indexed integer arrays nums1 and nums2, each of size n, and an integer diff.

You are given two 0-indexed integer arrays nums1 and nums2, each of size n, and an integer diff. Find the number of pairs (i, j) such that:

Return the number of pairs that satisfy the conditions.

Example 1

Input: nums1 = [3,2,5], nums2 = [2,2,1], diff = 1

Output: 3

Explanation: There are 3 pairs that satisfy the conditions: 1. i = 0, j = 1: 3 - 2 <= 2 - 2 + 1. Since i < j and 1 <= 1, this pair satisfies the conditions. 2. i = 0, j = 2: 3 - 5 <= 2 - 1 + 1. Since i < j and -2 <= 2, this pair satisfies the conditions. 3. i = 1, j = 2: 2 - 5 <= 2 - 1 + 1. Since i < j and -3 <= 2, this pair satisfies the conditions. Therefore, we return 3.

Example 2

Input: nums1 = [3,-1], nums2 = [-2,2], diff = -1

Output: 0

Explanation: Since there does not exist any pair that satisfies the conditions, we return 0.

Constraints

  • n == nums1.length == nums2.length
  • 2 <= n <= 10^5
  • -10^4 <= nums1[i], nums2[i] <= 10^4
  • -10^4 <= diff <= 10^4
