看不懂

这样做的： #include <iostream> using namespace std; int main() { int x, y; if (cin >> x >> y && 1 <= x && x <= 1000 && 1 <= y && y <= 1000) { int a = 4 * x - y; int b = a / 2; if (a % 2 == 0 && b >= 0 && b <= x) { cout << b << endl << x - b << endl; } else { cout << "No solution" << endl; } } else { cout << "Invalid input" << endl; } return 0; }

1+1=1就可以做了

放这么多测试点干嘛😅😅😅

这是错在哪了？？？ #include<iostream> using namespace std; int main(){ long long n; cin>>n; long long sum=0; while(n!=0){ sum+=n%10; n/=10; } if(sum%9==0) cout<<"YES"; else cout<<"NO"; return 0; }
