Reverse Linked List
Reverse a singly linked list Example: [1,2,3,4,5] => [5,4,3,2,1]
Reverse Linked List is about exploring choices without getting lost—choose, recurse, undo, repeat. It's a great warm-up that builds structured exploration without a ton of moving parts. If you can explain your pruning, this stops feeling like brute force.

Meet Coco
Coco is an AI study partner, not a person. She listens while you explain your code, asks what a line does and never hands you the fix. Typing with Coco is free when you sign in, up to a daily limit. Talking with her out loud comes with the $79 pack. Anyone can open the editor and run their code.
