Linked List Visualizer

Visualize node creation, pointer changes, and execution steps while learning how singly linked lists behave.

Difficulty: Beginner

Practice reversing a singly linked list and see how head, temp, and prev change at every step.

Difficulty: Beginner

Learn the simplest linked list loop correctly and understand what each move to next actually means.

Difficulty: Beginner

Practice inserting new nodes into the middle of a list without breaking the existing chain.

Difficulty: Intermediate

Practice removing or skipping a node by rewiring around it while keeping the rest of the list intact.

Difficulty: Intermediate

Use a simple box-based activity to discover head, next pointers, and traversal order without reading code first.
