Reverse a Linked List in c++ algorithm

Algorithm for reversing a linked list in C++:

  1. Initialize three pointers, prev, curr, and next.
  2. Set prev to NULL, curr to head of the linked list, and next to head->next.
  3. Iterate through the list using a while loop, where the condition is that curr is not equal to NULL.
  4. In each iteration, set curr->next to prev and update prev to curr and curr to next.
  5. If next is not equal to NULL, set next to next->next.
  6. Finally, set head of the linked list to prev.

This algorithm has a time complexity of O(n) and a space complexity of O(1), where n is the number of nodes in the linked list. It is an efficient algorithm for reversing a linked list in C++.
