169\. Majority Element

Easy

Given an array `nums` of size `n`, return _the majority element_.

The majority element is the element that appears more than `⌊n / 2⌋` times. You may assume that the majority element always exists in the array.

**Example 1:**

**Input:** nums = [3,2,3]

**Output:** 3 

**Example 2:**

**Input:** nums = [2,2,1,1,1,2,2]

**Output:** 2 

**Constraints:**

*   `n == nums.length`
*   1 <= n <= 5 * 104
*   -231 <= nums[i] <= 231 - 1

**Follow-up:** Could you solve the problem in linear time and in `O(1)` space?
