Contains Duplicate. Easy. Given an integer array nums, return true if any value appears at least twice in the array, and return false if every element is distinct. Example 1: Input: nums = [1,2,3,1] Output: true. Example 2: Input: nums = [1,2,3,4] Output: false. Example 3: Input: nums = [1,1,1,3,3,4,3,2,4,2] Output: true. Constraints:
