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[][] arr = new int[n][n];

        int count = 1;

        for (int i = 0; i < n; i++) {
            for (int j = 0; j <= i; j++) {
                arr[i][j] = count++;
            }
        }

        //列
        int rank = 0;
        //行
        int row = 0;

        while (true) {
            System.out.print(arr[row][rank] + " ");
            rank++;
            row++;

            if (row == n && rank == 1) break;

            if (row >= n) {
                System.out.print("\n");
                row = n - rank + 1;
                rank = 0;
            }
        }
    }
}

用最笨的办法 先输入一个数组 然后想办法修改打印路径
