编写程序功能为完成a和b两个变量值互换 其中a=1b=2 输出结果要求一行输出a=2b=1

ChatGPT: 你好，我是C知道，有什么问题需要我回答吗？

用户：用Java设计一个一元稀疏多项式简单计算器。要求：(1)输入并建立两个多项式;(2)多项式a与b相加，建立和多项式c;(3)多项式a与b相减，建立差多项式d;(4)输出多项式a, b,c, d。输出格式:比如多项式a为: A(x)=c1xe1 c2xe2 ... cmxem， 其中，ci和ei分别为第i项的系数和指数，且各项按指数的升幂排列，即0≤e1<e2<...<em。

ChatGPT: 可以的，以下是Java代码示例：

import java.util.Scanner;

public class SparsePolynomialCalculator {
    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);

        // 输入多项式a
        System.out.print("请输入多项式a的项数：");
        int aSize = input.nextInt();
        int[] aCoefficients = new int[aSize];

        for (int i = 0; i < aSize; i++) {
            System.out.print("请输入第" + (i + 1) + "项的系数：");
            aCoefficients[i] = input.nextInt();
            System.out.print("请输入第" + (i + 1) + "项的指数：");
            aExponents[i] = input.nextInt();
        }

        // 输入多项式b
