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…

class Solution { public: bool isUgly(int num) { ) return false; ) return true; && num % == ) num /= ; && num % == ) num /= ; && num % == ) num /= ; ; } }; 所谓丑数,是指质因子只能是2,3,5中的.1认为也是丑数.…

Write a program to find the n-th ugly number. Ugly numbers are positive numbers whose prime factors only include 2, 3, 5. For example, 1, 2, 3, 4, 5, 6, 8, 9, 10, 12 is the sequence of the first 10 ugly numbers. Note that 1 is typically treated as an…

263. Ugly Number 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.…

263. Ugly Number 注意:1.小于等于0都不属于丑数 2.while循环的判断不是num >= 0, 而是能被2 .3.5整除,即能被整除才去除这些数 class Solution { public: bool isUgly(int num) { ) return false; == ) num /= ; == ) num /= ; == ) num /= ; ? true : false; } }; 264. Ugly Number II 用一个数组去存第n个前面的所有整数,然后…

编写程序判断给定的数是否为丑数.丑数就是只包含质因子 2, 3, 5 的正整数.例如, 6, 8 是丑数,而 14 不是,因为它包含了另外一个质因子 7.注意:    1 也可以被当做丑数.    输入不会超过32位整数的范围.详见:https://leetcode.com/problems/ugly-number/description/ Java实现: class Solution { public boolean isUgly(int num) { if(num<=0){ return f…

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. Example 1: Input: 6 Output: true Explanation: 6 = 2 × 3 Example 2: Input: 8 Output: true Explanation: 8 = 2…
