AI Practicer

Your challengeGiven an array of integers, return the length of the longest consecutive sequence in O(n) time.

I’m thinking of putting every number in a set first. Is that the right direction?

AI PracticerThat’s a strong start. Which numbers should begin a sequence, and how could that prevent duplicate work?

A deliberate practice loop

More reps. Better reasoning.

Choose your challenge

Set the topic, difficulty, and programming language that match what you want to learn.

Work it out loud

Explain your approach, test edge cases, and share code as you would in a technical interview.

Get the right nudge

Receive questions and incremental hints first, then a full explanation and complexity review when you ask.

Built for progress

A tutor that meets you at the whiteboard.

Every practice session is private to your account, so you can return to a hard problem, see your past reasoning, and keep building the habit of clear algorithmic thinking.
