今天用c语言写了有序链表的合并。
#include <stdio.h>
#include <stdlib.h>
typedef int ElementType;
typedef struct Node *PtrToNode;
struct Node {
    ElementType Data;
    PtrToNode   Next;
};
typedef PtrToNode List;

List Read(); /* 细节在此不表 */
void Print( List L ); /* 细节在此不表；空链表将输出NULL */

List Merge( List L1, List L2 );

int main()
{
    List L1, L2, L;
    L1 = Read();
    L2 = Read();
    L = Merge(L1, L2);
    Print(L);
    Print(L1);
    Print(L2);
    return 0;
}


List Merge( List L1, List L2 )
{
    List pa,pb,pc;
    pa=L1->Next;
    pb=L2->Next;
    List L=(List)malloc(sizeof(List));
    pc=L;
    while(pa&&pb)
    {
        if(pa->Data>pb->Data)
        {
            pc->Next=pb;
            pb=pb->Next;
        }
        else{
            pc->Next=pa;
            pa=pa->Next;
        }
        pc=pc->Next;
    }
    pc->Next=pa?pa:pb;
    L1->Next=NULL;
    L2->Next=NULL;
    return L;
}
