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.
Examples
Example 1
Input: nums = [1,2,3,1]
Output: true
Explanation:
The element 1 occurs at the indices 0 and 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
Constraints
1 <= nums.length <= 105-109 <= nums[i] <= 109
