Use Iterative Function to Reverse the Linked List in C++ We assume that the target object is a singly linked list and implement code snippets accordingly. At first, we need to look at the basic function utilities in the driver code implemented to demonstrate the example. ...

Reverse Linked List II Reverse a linked list from positionmton. Do it in-place and in one-pass. For example: Given1->2->3->4->5->NULL,m= 2 andn= 4, return1->4->3->2->5->NULL. Note: Givenm,nsatisfy the following condition:...
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...
