N-Repeated Element in Size 2N Array Lab

In this lab, you will work with a problem that focuses on finding the N-repeated element in an array of size 2N. You will be given an integer array nums with the following properties:

• nums.length == 2 * n.
• nums contains n + 1 unique elements.
• Exactly one element of nums is repeated n times.

Your task is to write a function, repeatedNTimes, that returns the element that is repeated n times.

Example 1:

Input: nums = [1,2,3,3] Output: 3

Example 2:

Input: nums = [2,1,2,5,3,2] Output: 2

Example 3:

Input: nums = [5,1,5,2,5,3,5,4] Output: 5

Constraints:

• 2 <= n <= 5000
• nums.length == 2 * n
• 0 <= nums[i] <= 104
• nums contains n + 1 unique elements and one of them is repeated exactly n times.

Challenges

1. Implement the repeatedNTimes function to find the N-repeated element in the array.
2. Ensure your function works correctly with the provided examples and any additional edge cases.
