编程算法之合并有序链表

一些应用软件中有用到升序链表,这个就需要程序员在应用软件开发的时候写好升序链表的代码,下面就是一组升序链表的代码,想要升序链表代码的小伙伴都拿去吧。
节点结构:
struct Node{
int val;
Node *next;
};
要求实现的函数:
Node* mergeList
代码:
/*

*/
/*eclipse cdt, gcc 4.8.1*/
#include
#include
using namespace std;
struct Node{
int val;
Node *next;
};
Node* mergeList {
if //递归的终止条件
return list_b;
else if
return list_a;
Node* pMergedHead = NULL; //合并后的链表
if {
pMergedHead = list_a; //指向头结点
pMergedHead->next = mergeList; //递归
} else {
pMergedHead = list_b;
pMergedHead->next = mergeList;
}
return pMergedHead;
}
Node* initList {
Node* pHead = new Node;
Node* pTemp = pHead;
for ;>
pTemp->val = vi[i];
if -1) { //非尾结点
Node* pNode = new Node;
pTemp->next = pNode;
pTemp = pTemp->next;
}
}
pTemp->next = NULL;
return pHead;
}
void printList {
Node* pTemp = L;
while {
std::cout << ptemp-="">val <<>
pTemp = pTemp->next;
}
std::cout << ptemp-="">val <<>
std::cout << std::endl="">
}
int main {
std::vector via = {1, 2, 3, 4, 5, 13};
std::vector vib = {2, 4, 5, 7, 9, 11};
Node* list_a = initList;
Node* list_b = initList;
std::cout << printlist="">
std::cout << printlist="">
Node* list_merge = mergeList;
std::cout << printlist="">
return 0;
}
