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:

• 1 <= nums.length <= 105
• -109 <= nums[i] <= 109
