#ifdef TEST
struct test {
    int ans;
} td[] = {
    {},
};

solver(char *s)
{
    int i;

    for(i = 0; i < strlen(s); i++)
        printf("x");
    printf("\n");
}

int
main(int argc, char *argv[])
{
    char S[101];
#ifdef TEST
    int tt;
    for(tt = 0; tt < sizeof(td) / sizeof(struct test); tt++) {
        solver();
        printf("%d\n", td[tt].ans);
