题解 | 蛇形矩阵

解题思路：

1. 整体并不难，核心是找出其中每一行之间的关系

import java.util.Scanner;


// 注意类名必须为 Main, 不要有任何 package xxx 信息
public class Main {
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        int n = in.nextInt();
        int c = 1;
        for (int i = 1; i <= n; i++) {
            System.out.print(c);
            int r = c;
            for (int j = i + 1; j <= n; j++) {
                System.out.print(" ");
                r = r + j;
                System.out.print(r);
            }
            System.out.println();
            c = c + i;
        }
    }
}
