169. Majority Element
Problem Statement :
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 :
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
-109 <= nums[i] <= 109
Solution (Py3) :
class Solution:
def majorityElement(self, nums: List[int]) -> int:
nums.sort()
return nums[len(nums)//2]
