#include<stdio.h>

    typedef int ElemType;
    typedef int status;
    # define LIST_INIT_SIZE 100
    # define OK 1
    # define OVERFLOW -1
    
    
    typedef struct{
        ElemType *elem;
        int length;
        int listsize;
    } SqList;
    
    //初始化线性表 
    status InitList_Sq(SqList *L){
        L-> elem  = (ElemType *)malloc(LIST_INIT_SIZE * sizeof(ElemType)) ;
        if(!L->elem) exit(OVERFLOW);
        L->length = 0;
        L->listsize = LIST_INIT_SIZE;
    
        return OK;
    }
    
    //创建有序表并为其赋值 
    void Create_sq(SqList *L){
        int i,n;
        printf("创建一个有序表！\n");
        printf("输入有序表里的元素个数：");
        scanf("%d",&n);
        L->length = n;
        for(i=0;i < n;i++){
            printf("输入第%d个元素的值：",i+1);
            scanf("%d",&L->elem[i]);
            printf("\n");

    //合并有序表 
    void Combine(SqList *la,SqList lb){
        int i = la->length - 1,j = lb.length - 1;       
    
        while(i >= 0 && j >= 0){
            if(la->elem[i] <= lb.elem[j]){
    
                if (!la->elem[i + 1])
                {               
                    la->elem[i + 1] = lb.elem[j];
    
                }else{
                    for (int k = la->length - 1; k >= i+1; --k)
                    {
                        la->elem[k +1] = la->elem[k];
                    }
                    la->elem[i + 1] = lb.elem[j];
                }
                la->length++;
                j--;                
    
            }else{
                i--;
            }
        }
    }
    
     main(){
        SqList sla;
        SqList slb;
        InitList_Sq(&sla);
        InitList_Sq(&slb);
    
        Create_sq(&sla);
        Create_sq(&slb);
    
        Combine(&sla,slb);
        Disp_Sq(sla);
    }
