Really dont know what the mistake???


int main() {
    char src[1405][1405];

    int n;
    cin >> n;

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

        }
    }

    int s = 0, S = 0;

    for(int i = 0; i < n; i++) {
        int tmps = 0, tmpS = 0;
        for(int z = 0; z < n; z++) {
            if(src[i][z] == 's') {
                tmps++;
                s = max(s, tmps);
                tmpS = 0;
            } else {
                tmpS++;
                S = max(S, tmpS);
                tmps = 0;
            }
        }
    }

                tmpS = 0;
            } else {
