Reverse a Linked List
đ Problem
Given a singly linked list, reverse it so the last node becomes the first.
đ§ Approach
Keep three pointers: previous (starts as NULL), current (starts at head), and next (temporary). For each node, save its next node, then point current's 'next' backward to previous, then move previous and current one step forward. Repeat until current becomes NULL â previous is now the new head.
