Once we initialize a new linked list and store the head of the list in a separate pointer, we can use it to reverse the contents. In this case, we implemented thereverseListfunction, which accepts a singleNode*argument and returns a new root node. At first, we duplicate the passed point...
Reverse Linked List II Q: 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 ...

Lists are sequence containers that are implemented as a doubly linked list and allow iteration in both directions. This post will discuss how to print a list in reverse order in C++. 1. Usingstd::copyfunction An elegant solution is to usestd::copyto copy the list’s contents to the output...
