题目大意：给出一个文本，存在“Apple”, “iPhone”, “iPod”, “iPad”的字样输出”MAI MAI MAI!“，碰到”Sony“则输出“SONY DAFA IS GOOD!”

解题思路：水题。

#include <cstdio>#include <cstring>#include <algorithm>using namespace std;const int maxn = 1e4;int len;char s[maxn];int judge (int k) {    if (k + 3 < len) {        if (strncmp(s + k, "iPod", 4) == 0 || strncmp(s + k, "iPad", 4) == 0)            return 1;    }    if (k + 4 < len) {         if (strncmp(s + k, "Apple", 5) == 0)            return 1;    }    if (k + 5 < len && strncmp(s + k, "iPhone", 6) == 0)        return 1;    if (k + 3 < len && strncmp(s + k, "Sony", 4) == 0)        return 2;    return 0;}int main () {    while (gets(s)) {        len = strlen(s);        for (int i = 0; i < len; i++) {            int k = judge(i);            if (k == 1)                printf("MAI MAI MAI!\n");            else if (k == 2)                printf("SONY DAFA IS GOOD!\n");        }    }    return 0;}
