2956. Find Common Elements Between Two Arrays

You are given two integer arrays nums1 and nums2 of sizes n and m, respectively. Calculate the following values:

• answer1: the number of indices i such that nums1[i] exists in nums2.
• answer2: the number of indices i such that nums2[i] exists in nums1.

Return [answer1, answer2].

Example 1:

Input: nums1 = [2,3,2], nums2 = [1,2]
Output: [2,1]

Example 2:
Input: nums1 = [4,3,2,3,1], nums2 = [2,2,5,2,3,6]
Output: [3,4]

Example 3:
Input: nums1 = [3,4,2,3], nums2 = [1,5]
Output: [0,0]

Constraints:
n == nums1.length
m == nums2.length
1 <= n, m <= 100
1 <= nums1[i], nums2[i] <= 100
