Write an algorithm to determine if a number is "happy". A happy number is a number defined by the following process: Starting with any positive integer, replace the number by the sum of the squares of its digits, and repeat the process until the…

今天先谈下弗洛伊德判环,弗洛伊德判环原来是在一个圈内有两人跑步,同时起跑,一人的速度是另一人的两倍,则那个人能在下一圈追上另一个人,弗洛伊德判环能解数字会循环出现的题,比如说判断一个链表是不是循环链表.在程序中具体表现为 one = change(one); //一倍速度 two = change(change(two));//两倍速度 即一倍速度的人调用生成函数change一次,两倍速度的人调用生成函数change两次. Leetcode 202 Happy Number 就是这样一道简单的题…

Write a program to check whether a given number is an ugly number. Ugly numbers are positive numbers whose prime factors only include 2, 3, 5. For example, 6, 8 are ugly while 14 is not ugly since it includes another prime factor 7. Note that 1 is ty…
