replace the number by the sum of the squares of its digits, and repeat the process until the number equals 1 (where it will stay), or it loops endlessly in a cycle which does not include 1. Those numbers for wh
squared repeatedly. If this method produces an infinite cycle of numbers containing 4, the number is known as an unhappy number. We will look at the implementation of finding out whether a number is a happy number in java.
以下是一个Python实现的Happy Number检测算法: 代码语言:txt 复制 def is_happy_number(n): def get_next(number): total_sum = 0 while number > 0: number, digit = divmod(number, 10) total_sum += digit ** 2 return total_sum seen = set() while n != 1 and n not in seen: seen.add...

leetcode:HappyNumber,House Robber 1.Happy Number 这个题中收获2点: 1.拿到题以后考虑特殊情况,代码中考虑1和4,或者说<6的情况,动手算下。(可能要在代码一步步测试中发现,目前还不知道怎么知道这些特殊情况) 2.数字的每一位时,n%10,n/10。(3/7的余数为3,7/3的余数为4) ...
