Test instructions: Returns the linked list of the specified segment [M,n], returning the chain header.Idea: The main trouble in the chain table head, if you want to start from the linked list, more special.At present, with the implementation of DFS, first find the location of the m-1, and then find the location of n+1,

Reverse a linked list from position m to n. Do it in-place and in one-pass. For example:Given1->2->3->4->5->NULL, M = 2 and n = 4, Return1->4->3->2->5->NULL. Note:Given m, n satisfy the following condition:1 ≤ m ≤ n ≤ length of list. It is still complicated to deal with this problem. Many boundary test cases need to be

->next = q;return head;}listnode* p = p1->next;listnode* q1 = q->next;Q->next = NULL;Doreverse (P);P1->next = q;P->next = Q1;return head;}}There are short implementations of code, but I am learning from others, execution speed is similar:listnode* dummy = new ListNode (0);Dummy->next = head;ListNode *lefti = dummy;for (;--m;--n) Lefti = lefti->next;ListNode *cur = lefti->next, *rtail = cur, *pre = nullptr;while (n--) {listnode* NXT = cur->next;Cur->next = pre;Pre = cur;cur = NXT;}Rtail->next = c

Reverse a linked list from position m to N. Do it in-place and in One-pass.For example:Given 1->2->3->4->5->NULL , m = 2 and n = 4,Return 1->4->3->2->5->NULL .Note:Given m, n satisfy the following condition:1 ≤ m ≤ n ≤length of list.It is strange why there is not one of the inverted list, it comes to this inverted

The reverse structure of the linked list basically repeats the contents of the basic linked list. For example, when a basic linked list is created, the
