题目链接: http://acm.hdu.edu.cn/showproblem.php?pid=3071 题目大意: 给定一个长度为n的序列m次操作,操作的种类一共有三种 查询 L :查询一个区间的所有的数的最小公倍数modp G :查询一个区间的所有的数的最大公约数modp 修改 C :将给定位置的值修改成x 解题思路: 注意数据范围,每个数字不超过100,所以100以内的质因子最多25个,如果直接求解lcm和gcd的话,long long也是存不下的,所以采用存储质因子的指数,但是如果每个节…
题解: A 喵哈哈村的跳棋比赛 题解:其实我们要理解题意就好了,画画图看看这个题意.x<y,那么就交换:x>y,那么x=x%y. 如果我们经过很多次,或者y<=0了,那么就会无限循环. #include<iostream> #include<cstdio> #include<cstring> using namespace std; long long x,y; void work(){ while(1){ if(x==0){ cout<<…
