排序 --- 6.2 Merge Two Sorted Lists || 6.3 Merge k Sorted Lists --- 图解
1. 合并两个有序链表
/**********************************************************************************************************
Merge two sorted linked lists and return it as a new list. e new list should be made by splicing
together the nodes of the first two lists.
**********************************************************************************************************/
class Solution{
public:ListNode *mergeTwoLists(ListNode*l1 , ListNode *l2){ListNode head(-1);for(ListNode * p = &head;l1 != nullptr || l2 != nullptr;p = p->next){int val1 = l1 == nullptr ? INT_MAX : l1->val;int val2 = l2 == nullptr ? INT_MAX : l2->val;if(val1 <= val2){p->next = l1;l1 = l1->next;}else{p->next = l2;l2 = l2->next;}}return head.next;}
};
2. 合并k个有序链表
class Solution{
public:ListNode *mergeTwoLists(ListNode*l1 , ListNode *l2){ListNode head(-1);for(ListNode * p = &head;l1 != nullptr || l2 != nullptr;p = p->next){int val1 = l1 == nullptr ? INT_MAX : l1->val;int val2 = l2 == nullptr ? INT_MAX : l2->val;if(val1 <= val2){p->next = l1;l1 = l1->next;}else{p->next = l2;l2 = l2->next;}}return head.next;}ListNode *mergeKlists(vector<ListNode *>&Lists){if(Lists.size() == 0 ) return nullptr;ListNode * p = Lists[0];for(int i = 0;i < Lists.size(); i++){p = mergeTwoLists(p, Lists[i]);}}
