不喜欢if-else的有福了（bushi)

#include <bits/stdc++.h>

int main(){
    int a, b;
    scanf("%d", &a);
    b = !(a % 2) + (a > 4 && a <= 12);
    printf("%d %d %d %d", b == 2, !!b, b == 1, !b);
}

#include<bits/stdc++.h> using namespace std; int main() { int x; cin>>x; if(x%20 && (x>4 && x<=12)) { cout<<1<<" "; } else { cout<<0<<" "; } if(x%20 || (x>4 && x<=12)) { cout<<1<<" "; } else { cout<<0<<" "; } if((x%2==0 && (x<=4 || x>12)) || (x%2!=0 && (x>4 && x<=12))) { cout<<1<<" "; } else { cout<<0<<" "; } if(x%2!=0 && (x<=4 || x>12)) { cout<<1<<" "; } else { cout<<0<<" "; } return 0; }
