使用字典dic = {},遍历 numbers数组,将每一个元素设为key 然后如果该元素不在dic中, 将key对应的值置1 ,拖过该元素在dic中,则key对应的值+=1
再次遍历number ,如果dic中有key 对应的值不为1,则将该值赋予
duplication[0] = i
j
# -*- coding:utf-8 -*- class Solution: # 这里要特别注意~找到任意重复的一个值并赋值到duplication[0] # 函数返回True/False def duplicate(self, numbers, duplication): # write code here dic = {} for i in numbers: if i not in dic: dic[i] = 1 else: dic[i] +=1 for i in numbers: if dic[i] !=1: duplication[0] = i return True return False
