Intersection of Two Arrays - Given two integer arrays nums1 and nums2, return an array of their intersection. Each element in the result must be unique and you may return the result in any order. Example 1: Input: nums1 = [1,2,2,1], nums2 = [2,2] Output: [2] Example 2: Input: nums1 = [4,9,5], nums2 = [9,4,9,8,4] Output: [9,4] Explanation: [4,9 ...
Intersection of Two Arrays II - Given two integer arrays nums1 and nums2, return an array of their intersection. Each element in the result must appear as many times as it shows in both arrays and you may return the result in any order.

350. Intersection of Two Arrays II ¶ Approach 1: Hash Table¶ Time: $O(m + n)$ Space: $O(\min(m, n))$
To find out the intersection of two arrays (nums1 and nums2) we can first store the count of each element of one array (let nums1) using a Hash map. Then we can traverse through the second array ( nums2 ) and for each element in nums2 we would check if count of that element in nums1 is positive or not.
