Linked lists, step by step
No indexes, only pointers. See why that makes traversal slower than an array but insertion and deletion faster, once you're already at the right node.
A scripted walkthrough: traverse a list, insert at the head, insert in the middle, then delete a node — the four operations that define how a linked list differs from an array.
A
B

Step 1 of 9
A singly linked list: A → B → C → null. Each node holds a value and a pointer to the next node — there's no index-based access like an array.
