The second approach is to re-insert m to n to the front of m. Careful boundary. First thought:1 class Solution {2 public: 3 ListNode * reverseList (ListNode * head) 4 {5 if (head

Given a singly linked list l: l0→l1→ ... →ln-1→lN,Reorder it to: l0→ln→l1→ln-1→l2→l N-2→ ...You must does this in-place without altering the nodes ' values.For example,Given {1,2,3,4} , reorder it to {1,4,2,3} .Problem solving idea One:Each time ln is changed to the front, I get l0→ln→l1→l2→L3→, Then use the same operation for L1, the Java implementation is as follows:public void Reorderlist (ListNode head) {ListNode headcopy = head;while (headcopy! = NULL headcopy.next! = null amp; HeadCopy.ne

First, the topic1, examining　　2. AnalysisGive a list of one-way lists, reorder them, and sort the rules as above.Second, the answer1, Ideas:Method One,Watch the list of reordered links above. Can be divided into three steps.①, find the middle node;②, flip the linked list in the back part.③, inserts a node in the linked list in the front part of the list.
