codechef LUCKYSTR - "little elephant and strings" solution: http://ideone.com/DtYOZ7

#include <iostream>

#include <cstdio>

#include <cstring>

using namespace std;

int main() {

int k, n, flag;

char f[55][55], s[55];

scanf("%d%d", &k, &n); 

for(int i=0; i<k; i++) scanf("%s", f[i]);

for(int i=0; i<n; i++) {

scanf("%s", s);

flag=0;

if(strlen(s)>=47) printf("Good\n");

else {

for(int j=0; j<k; j++) {

if(strstr(s, f[j])) {

flag=1;

break;

}

}

if(flag) printf("Good\n");

else printf("Bad\n");

}

}

}

note: i was damn tired of coding bugs, when i was trying to solve this problem. add to that previous days i had failed to solve "arrange" and "equation" problems at codechef. but then i came up with "strstr" function in <cstring> header : http://en.cppreference.com/w/cpp/string/byte/strstr
