169. Majority Element
Given an array
numsof sizen, 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: 3Example 2:
Input: nums = [2,2,1,1,1,2,2]
Output: 2
def majorityElement(self, nums: List[int]) -> int:
dic = {}
for num in nums:
if num in dic:
dic[num]+=1
else:
dic[num]=1
keymax = max(zip(dic.values(), dic.keys()))[1]
return keymax
