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?
