为什么我的在编译器上对了，但在落谷上就全是wrong呢

#include <stdio.h>
#include <string.h>

int compute (int i) {
int count = 0;
if (i <= 0) {
count++;
}
while (i) {
i /= 10;
count++;
}

return count;

}

int main () {
int n, i, t, j, count;
scanf("%d", &n);
char a[51][100];
int b[51][100] = {0};
getchar();
for (i = 0; i < n; i++) {
gets(a[i]);
}
for (i = 0; i < n; i++) {
count = 1;
for (j = 0; j < strlen(a[i]); j++) {

continue;

        } else {

    }
}







return 0;

}

比如题目可能要求输出没有空行。你这所有printf都带\n可能就不行了
