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.length
  • 1 <= n <= 5 * 104
  • -109 <= nums[i] <= 109

Solution

class Solution(object):
    def majorityElement(self, nums):
        """
        :type nums: List[int]
        :rtype: int
        """
        uniques = list(set(nums))
        for i in uniques:
            if nums.count(i) > len(nums) / 2:
                return i
