编写不难 难在找规律

已AC，放心食用

#include <iostream>
using namespace std;
int main() {
    int n;
    cin >> n;
    int a[n][n];
    for (int i = 1;i <= n;++i){
        int x = n;
        int f = i;
        if (i == 1){
            for (int j = 1;j <= n;++j){
                a[i][j] = f;
                f += x;
                x --;
            }
        }
        else{
            for (int j = 1;j <= i - 1;++j){
                a[i][j] = a[j][i];
            }
            for (int j = i;j <= n;++j){
                a[i][j] = f;
                f += x;
                x --;
            }
        }
    }
    for (int i = 1;i <= n;++i){
        for (int j = 1;j <= n;++j){
            if (a[i][j] / 10 > 0){
                cout << "   " << a[i][j];
            }
            else{
                cout << "    " << a[i][j];
            }
        }
        cout << endl;
    }
    return 0;
}

好像UI变了 注释写不上

#include <iostream> using namespace std; int main() { int n; cin >> n; int a[n][n]; for (int i = 1;i <= n;++i){ int x = n; int f = i; if (i == 1){ for (int j = 1;j <= n;++j){ a[i][j] = f; f += x; x --; } } else{ for (int j = 1;j <= i - 1;++j){ a[i][j] = a[j][i]; } for (int j = i;j <= n;++j){ a[i][j] = f; f += x; x --; } } } for (int i = 1;i <= n;++i){ for (int j = 1;j <= n;++j){ if (a[i][j] / 10 > 0){ cout << " " << a[i][j]; } else{ cout << " " << a[i][j]; } } cout << endl; } return 0; }
