题目大意:题目描述了一大堆.....然而并没什么用,其实就是让求给的所有字符串里面有多少个"doge",不区分大小写.   代码如下: ====================================================================================================================== #include<stdio.h> #include<string.h> #include&…

就是求出现了多少次doge 不区分大小写  巧用字符串函数 isalpha 判断是否是字母 tolower 转换为小写字母 toupper 转换为大写字母 strncmp字符串比较函数  能限制比较的长度 #include <iostream> #include <cstdio> #include <sstream> #include <cstring> #include <map> #include <cctype> #includ…

HDU 4847 Wow! Such Doge! pid=4847" style="">题目链接 题意:给定文本,求有几个doge,不区分大写和小写 思路:水题.直接一个个读字符每次推断就可以 代码: #include <stdio.h> #include <string.h> char c; char a[5]; int main() { a[5] = '\0'; int ans = 0; while ((c = getchar()) != E…

Wow! Such Doge! 题意:给定的字符串中doge出现了多少次,直接模拟即可,不用KMP. char s[N]; int main() { // int n; int ans=0; while(gets(s)) { for(int i=0; s[i]!='\0'; i++) if(s[i]>='A'&&s[i]<'z') { if(s[i]=='d'||s[i]=='D') { if(s[i+1]=='o'||s[i+1]=='O') { if(s[i+2]=='g'…

题意:定义一个a*b=字符串a连接字符串b:给你一个字符串s,问你这个字符串最多能用多少个字符串t连接得到:例如:aaaa=4个a构成: 解题思路:kmp水题,next数组除了查找字串以外最广泛的一种用法,用来判定一个串是不是循环串,如果是,输出原串的长度/最小的循环节,否则,输出1就行了: 代码: #include<iostream> #include<cstdio> #include<cstring> #define maxn 1000500 using names…

题目:hdu4847:Wow! Such Doge! 题目大意:在给出的段落里面找出"doge"出现的次数.大写和小写都能够. 解题思路:字符串匹配问题,能够在之前将字母都转换成统一格式. 代码: #include <stdio.h> #include <string.h> const int N = 1e6; char str[N]; const char *s1 = "doge"; int find () { int sum = 0; c…
