LeetCode 169 - Majority Element Problem

Problem Statement

Given an array of size n, find the majority element. The majority element is the element that appears more than ⌊ n/2 ⌋ times.

You may assume that the array is non-empty and the majority element always exist in the array.

Example 1:

Input: [3,2,3]

Example 2:

Input: [2,2,1,1,1,2,2]
Output: 2


class Solution: def majorityElement(self, nums: List[int]) -> int: n = len(nums) target = n//2 counter = {} for num in nums: try: counter[num]+=1 except: counter[num] = 1 if counter[num]>target: return num
