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]
Output: 3
Example 2:
Input: [2,2,1,1,1,2,2]
Output: 2
My code:
class Solution(object):
def majorityElement(self, nums):
"""
:type nums: List[int]
:rtype: int
"""
tmp_dict={}
for i in range(len(nums)):
if nums[i] not in tmp_dict:
tmp_dict[nums[i]]=1
else:
tmp_dict[nums[i]]+=1
if tmp_dict[nums[i]]>len(nums)/2:
return nums[i]
return None
