Be very careful that n1's next must point to Ø. If you forget about this, your linked list has a cycle in it. This bug could be caught if you test your code with a linked list of size 2. publicListNodereverseList(ListNodehead){if(head==null||head.next==null)returnhead;ListNodep...
leetcode 206. Reverse Linked List 反转字符串 Reverse a singly linked list. 反转链表,我这里是采用头插法来实现反转链表。 代码如下: AI检测代码解析 /*class ListNode { int val; ListNode next; ListNode(int x) { val = x; } } */ public class Solution { public ListNode reverseList(ListNode hea...
We will see how to reverse a linked list in java. LinkedList is a linear data structure where an element is a separate object with a data part and address part.
Here is a nice diagram that explains thealgorithm to reverse a linked listwithout recursion in Java: You can see that links are reversed in each step using the pointer's previous and next. This is also known as the iterative algorithm to reverse the linked list in Java. For the recursive...
The reversal algorithm can be described as follows: We store the next node pointer in a temporary variable (next) and assign thenullptrvalue to the original one. As a result, the originalheadnode will be pointing to thenullptras its next node in the list. Next, we update theheadvariable ...
1.使用string.h中的strrev函数 strrev(数组名);即可实现字符串的反转,2.使用algorithm中的reverse函数 2.使用algorithm中的reverse函数 这两个函数在我测试的时候出现了两种完全不同的情况 1.strrev函数只对字符数组有效,对string类型是无效的。 2.reverse函数是反转容器中的内容,对字符数组无效。 转...35...
