Given an array nums of size n, return the majority element.
The majority element is the element that appears more than ⌊n / 2⌋ times in the array. You may assume that the majority element always exists in the array.
Example 1:
Input: nums = [5,5,1,1,1,5,5]
Output: 5Example 2:
Input: nums = [2,2,2]
Output: 2Constraints:
1 <= nums.length <= 50,000-1,000,000,000 <= nums[i] <= 1,000,000,000Follow-up: Could you solve the problem in linear time and in O(1) space?
