解题思路:

注意事项:

参考代码:

import java.util.Scanner;

public class Main {

public static void main(String[] args) {

Scanner scanner=new Scanner(System.in);

int n=scanner.nextInt();

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

arr[0][0]=1;

System.out.print(arr[0][0]+" ");

for(int i=0;i<n-1;i++){

arr[i+1][0]=arr[i][0]+i+1;

for(int j=0;j<n-i-1;j++){

arr[i][j+1]=arr[i][j]+j+i+2;

System.out.print(arr[i][j+1]+" ");

}

System.out.println();

System.out.print(arr[i+1][0]+" ");

}

System.out.println();

}

}
