Problem
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.length1 <= n <= 5 * 104-109 <= nums[i] <= 109
Follow-up: Could you solve the problem in linear time and in
O(1) space?
