Given an array nums of size n, return the majority element.

The majority element is the element that appears more than [n/1] times. You may assume that the majority element always exists in the array.

Output: 3

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

Constraints:
n == nums.length
1 <= n <= 5 * 10**4
-10**9 <= nums[i] <= 10**9
