I don't understand what's wrong with my code. Help me pls. Thnx in advance.

#include<stdio.h>

int main(){
    int L, H;
    scanf("%d%d", &L, &H);
    printf("%d %d ", 10 - L, 10 - H);

    return 0;
}

It said not more than 10 cans...
thus there could be less than 10 cans

Once Harry and Larry shoot a common can...
you gotta consider that too...
