    3164 - Find the Number of Good Pairs II\.

    Medium

    You are given 2 integer arrays nums1 and nums2 of lengths n and m respectively. You are also given a positive integer k.

    A pair (i, j) is called good if nums1[i] is divisible by nums2[j] * k (0 <= i <= n - 1, 0 <= j <= m - 1).

    Return the total number of good pairs.

    Example 1:

    Input: nums1 = 1,3,4, nums2 = 1,3,4, k = 1

    Output: 5

    Explanation:

    The 5 good pairs are (0, 0), (1, 0), (1, 1), (2, 0), and (2, 2).

    Example 2:

    Input: nums1 = 1,2,4,12, nums2 = 2,4, k = 3

    Output: 2

    Explanation:

    The 2 good pairs are (3, 0) and (3, 1).

    Constraints:

    • <code>1 <= n, m <= 10<sup>5</sup></code>

    • <code>1 <= nums1i, nums2j<= 10<sup>6</sup></code>

    • <code>1 <= k <= 10<sup>3</sup></code>
