python code：

class Solution:
# @param {integer[]} nums
# @return {integer}
def majorityElement(self, nums):
　　b={}
　　for eachnum in nums:
　　　　if eachnum not in b:
　　　　　　b[eachnum]=1　　#统计每个数值出现的次数，找出出现次数最多的，返回此数值
　　　　else:
　　　　　　b[eachnum]+=1
　　for eachnum in b:
　　　　if b[eachnum]==max(b.values()):
　　　　　　return eachnum
