丑数系列的题看这一道就可以了 /* 和ugly number2差不多,不过这次的质因子多了,所以用数组来表示质因子的target坐标 target坐标指的是这个质因子此次要乘的前任丑数是谁 */ public int nthSuperUglyNumber(int n, int[] primes) { //记录相乘坐标,存的是每个质因子对应相乘搭档在丑数数组中的下标 int[] target = new int[primes.length]; //动态规划数组 int[] dp = new int…
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…
