C语言训练-尼科彻斯定理 （Java代码）代码挺短，可以参考一下

解题思路:

注意事项:

参考代码:

import java.util.Scanner;

public class Main1127 {

    public static void main(String[] args) {

        Scanner sc = new Scanner(System.in);

        int x = sc.nextInt();

        System.out.print("" + x + '*' + x + '*' + x + '=' + (int) Math.pow(x, 3) + '=');

        for (int i = 0; i < 2 * x; i += 2) {

            if (i == 2 * x - 2) {

                System.out.print("" + ((int) Math.pow(x, 2) - x + 1 + i));

            } else {

                System.out.print("" + ((int) Math.pow(x, 2) - x + 1 + i) + '+');

            }

        }

    }
