2956. Find Common Elements Between Two Arrays
Easy
10 Points
Array
Hash Table
You are given two integer arrays nums1 and nums2 of sizes n and m, respectively. Calculate the following values:
Return [answer1,answer2].
Examples
Example 1
Input: nums1 = [2,3,2], nums2 = [1,2]
Output: [2,1]
Explanation:
Example 2
Input: nums1 = [4,3,2,3,1], nums2 = [2,2,5,2,3,6]
Output: [3,4]
Explanation:
The elements at indices 1, 2, and 3 in nums1 exist in nums2 as well. So answer1 is 3.
The elements at indices 0, 1, 3, and 4 in nums2 exist in nums1 . So answer2 is 4.
Example 3
Input: nums1 = [3,4,2,3], nums2 = [1,5]
Output: [0,0]
Explanation:
No numbers are common between nums1 and nums2 , so answer is [0,0].
Constraints
n == nums1.lengthm == nums2.length1 <= n, m <= 1001 <= nums1[i], nums2[i] <= 100
