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
Explanation: The element 1 appears at index 0 and index 3.
Example 2:
Input: nums = [1,2,3,4]
Output: false
Explanation: All elements are distinct.
Example 3:
Input: nums = [1,1,1,3,3,4,3,2,4,2]
Output: true
Explanation: Multiple elements appear more than once.
1 <= nums.length <= 10^5-10^9 <= nums[i] <= 10^9
