顺序赋值再输出

解题思路:顺序赋值
注意事项:

参考代码:

import java.util.Scanner;

public class Main {

public static void main(String[] args) {

Scanner sc = new Scanner(System.in);

int s = sc.nextInt();

int a = 1;

int [][]arr= new int[s][s];

for (int i = 0; i <s; i++) {

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

arr[i-j][j]=a;

a++;

}

}

for (int i = 0; i < arr.length; i++) {

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

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

}

System.out.println();

}

}

}
