Given an array of integers 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

Constraints: 1 <= nums.length <= 100 -1000 <= nums[i] <= 1000
