The least common multiple (LCM) of a set of positive integers is the smallest positive integer which is divisible by all the numbers in the set. For example, the LCM of 5, 7 and 15 is 105.   InputInput will consist of multiple problem instances. The…

题目:http://acm.hdu.edu.cn/showproblem.php?pid=2028 思路:最一想到的就是暴力求解,从1开始一直到最后的答案,一直来除以给出的数列的数,直到余数为0:当然我们能升级,以输入的第一个数为初值,来除以数列,不行再进行翻倍操作,这样能减少循环的次数 开始用了break和continue ,最后发现复杂了. 复习哈C语言break continue break:强行退出循环,不再执行本次循环,即跳出此循环 (CPU直接结束这一个循环,运行下面的代码) con…

题目:Least common multiple 链接:http://acm.hdu.edu.cn/showproblem.php?pid=4913 题意:有一个集合s,包含x1,x2,...,xn,有xi=2^ai * 3^bi,然后给你a数组和b数组,求s所有子集合的最小公倍数之和.比如S={18,12,18},那么有{18},{12},{18},{18,12},{18,18},{12,18},{18,12,18},所以答案是174. 思路: 1. 最小公倍数,因为xi只包含两个质因子2.3…
