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.

\n\n

 

\n

Example 1:

\n\n
\nInput: nums1 = [1,2,2,1], nums2 = [2,2]\nOutput: [2]\n
\n\n

Example 2:

\n\n
\nInput: nums1 = [4,9,5], nums2 = [9,4,9,8,4]\nOutput: [9,4]\nExplanation: [4,9] is also accepted.\n
\n\n

 

\n

Constraints:

\n\n\n", "translatedTitle": "两个数组的交集", "translatedContent": "

给定两个数组 nums1 和 nums2 ,返回 它们的 交集 。输出结果中的每个元素一定是 唯一 的。我们可以 不考虑输出结果的顺序

\n\n

示例 1:

\n\n
\n输入:nums1 = [1,2,2,1], nums2 = [2,2]\n输出:[2]\n
\n\n

示例 2:

\n\n
\n输入:nums1 = [4,9,5], nums2 = [9,4,9,8,4]\n输出:[9,4]\n解释:[4,9] 也是可通过的\n
