题目:http://acm.hdu.edu.cn/showproblem.php?pid=1715 本题采用大数加法即可解决.采用100000000进制速度更快. C++代码如下: #include<iostream> #include<string.h> using namespace std; #define maxn 1000 + 1//最多算到f(1000) #define len 1000//结果最多有1000*8位 int a[maxn][len]; int main(…
题目;http://acm.hdu.edu.cn/showproblem.php?pid=5455 题意就是找出所给字符串有多少个满足题目所给条件的子串,重复的也算,坑点是如果有c,f以外的字符也是不满足条件的,还有我被坑了的地方就是当输入很多f的时候,我尽然脑抽的 认为这是不满足条件的,注意这两点就行了,直接暴力 #include<cstdio> #include<cstring> using namespace std; int main() { int t,i,j,x,y,k…
