我比赛代码

#include <iostream>
using namespace std;

typedef long long ll;

int main() {
    int N;
    ll X, D;
    cin >> N >> X >> D;
  
    if (N == 1) {
       
       cout << "-1" << endl;
       
        return 0;
    }
    
    cout << "2 " << 4*N+1 << endl;
    ll s=0;
    for (int i = 0; i < N; i++) {
        ll start = X + i*(4*D+D);
        cout << start-s*N << " " << start+1*N -s*N<< " " << start+2*N -s*N << " " << start+3*N -s*N << endl;
        s++;
    }
    
    return 0;
}

考完改的

#include <iostream>
using namespace std;
typedef long long ll;
int main() {
    int N;
    ll X, D;
    cin >> N >> X >> D;
    if (N == 1) {
       cout << "-1" << endl;
        return 0;
    }
    
    cout << "2 " << 4*N+1 << endl;
    for (int i = 0; i < N; i++) {
        ll start = X + i*D;
        if(i==1)start += N * D;
        for(int j=0;j<4;j++){
            cout << start+j*N *D <<" ";
        }
        cout<<'\n';
    }
    
    return 0;
}
