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 indicesisuch thatnums1[i]exists innums2.answer2: the number of indicesisuch thatnums2[i]exists innums1.
Return [answer1, answer2].
Example 1
Input
nums1 = [2,3,2], nums2 = [1,2]Output
[2,1]The value 2 appears at indices 0 and 2 in
nums1, and the value 2 at index 1 in nums2 exists in nums1.Example 2
Input
nums1 = [4,3,2,3,1], nums2 = [2,2,5,2,3,6]Output
[3,4]The elements at indices 1, 2, and 3 in
nums1 exist in nums2, and the elements at indices 0, 1, 3, and 4 in nums2 exist in nums1.Constraints
- n == nums1.length
- m == nums2.length
- 1 <= n, m <= 100
- 1 <= nums1[i], nums2[i] <= 100
