Merge two sorted linked lists and return it as a new list. The new list should be made by splicing together the nodes of the first two lists.
合并两个已经排序好的链表。
class Solution
{
public:
ListNode* mergeTwoLists(ListNode* l1, ListNode* l2)
{
ListNode* head=new ListNode(0);
ListNode* p=head;
while(l1!=NULL&&l2!=NULL)
{
if(l1->val>l2->val)
{
p->next=l1;
l1=l1->next;
}
else
{
p->next=l2;
l2=l2->next;
}
p=p->next;
p->next=NULL;
}
if(l1!=NULL)
{
p->next=l1;
}
if(l2!=NULL)
{
p->next=l2;
}
return head->next;
}
};
