该博客介绍了一个C语言程序，用于实现两个多项式的相加。程序首先将输入的两个多项式合并成一个链表，然后进行排序和同类项合并。通过读入多项式，进行一系列的链表操作，最终输出相加后的结果。

Add Two Polynomials

Write a function to add two polynomials. Do not destroy the input. Use a linked list implementation with a dummy head node. Note: The zero polynomial is represented by an empty list with only the dummy head node.

Format of functions:

Polynomial Add( Polynomial a, Polynomial b );
where Polynomial is defined as the following:

typedef struct Node *PtrToNode;
struct Node {
int Coefficient;
int Exponent;
PtrToNode Next;
};
typedef PtrToNode Polynomial;
/* Nodes are sorted in decreasing order of exponents.*/
The function Add is supposed to return a polynomial which is the sum of a and b.

Sample program of judge:

#include <stdio.h>
#include <stdlib.h>
typedef struct Node *PtrToNode;
struct Node {
int Coefficient;
int Exponent;
PtrToNode Next;
};
typedef PtrToNode Polynomial;

Polynomial Read(); /* details omitted */
void Print( Polynomial p ); /* details omitted */
Polynomial Add( Polynomial a, Polynomial b );

int main()
{
Polynomial a, b, s;
a = Read();
b = Read();
s = Add(a, b);
Print(s);
return 0;
}

/* Your function will be put here */

Sample Input:

4
3 4 -5 2 6 1 -2 0
3
5 20 -7 4 3 1

Sample Output:
