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`
