Step-by-step animation of a singly linked list: insert at head / tail / position, delete by value, search and reverse — with node + pointer diagrams, a live step log and the current list state.
Enter a value, then pick an operation: Insert head / tail prepends or appends a node; Insert at splices a node at the given 0-based position (needs both Value and Position). Delete removes the first node matching the value; Search walks the list highlighting each visited node. Reverse flips every pointer in place. Each operation plays as a frame-by-frame animation on the node + arrow diagram, writes a line to the step log, and updates the current list (HEAD → … → NULL). Pure front-end — no data leaves your browser.
Where linked lists are used
• Stacks, queues and deque implementations
• Undo / redo history and browser back-forward chains
• Free-list memory allocation and block pools
• Music playlists and image carousels (next-pointer chains)
• Separate chaining in hash tables for collision buckets
• Sparse matrices and polynomial arithmetic
• LRU cache eviction ordering
