データ構造とアルゴリズムのクイズ - 選択問題・正誤問題・出力

スタック、木、グラフ、計算量をリアルタイムで

The Data Structures Quiz on MindLoop is a live multiplayer knowledge game covering the foundations every engineer is expected to know cold - arrays, linked lists, stacks, queues, hash tables, trees, heaps, graphs, and the time and space complexity that separates a good solution from a slow one. Run it as a multiple-choice Quiz for concept recall, a rapid True/False round for fast participation, or an Output Based mode where players trace an algorithm and predict its result or final state. The Data Structures Quiz is a staple of DSA courses, competitive programming clubs, and coding-interview preparation. Because the leaderboard updates on every answer, hosts can instantly see who has internalized Big-O reasoning and traversal logic and who is still pattern-matching - making group revision sessions dramatically more targeted.

Data Structures Quiz

How to Play

1
The host creates a Data Structures room and picks a mode - quiz, true/false, or output
2
Players join with the room code from any device
3
Questions on data structures, algorithms, and complexity appear one at a time
4
In output mode, trace the algorithm and predict its result or final state
5
Faster correct answers score more on the live leaderboard
6
A summary highlights strong and weak topic areas at the end

Choose your question mode

Run Data Structures Quiz three ways - a concept quiz, a rapid true/false round, or an output-prediction challenge. Each mode opens the create flow with the right setup ready to go.

Concept Sprint

Quiz

Data Structures fundamentals, APIs, and practical recall rounds from the seeded pool.

Create a room Rapid Fire

True / False

Data Structures fact checks for people who answer first and think later.

Create a room Trace Mode

Output Based

Predict Data Structures execution before the runtime judges everyone equally.

Professors teaching data structures and algorithms courses
Competitive programming clubs and DSA study groups
Engineers preparing for coding interviews at any level
Bootcamp instructors running algorithm assessment sessions
Students reinforcing Big-O reasoning and traversal logic

Why Play?

Three modes in one - concept quiz, rapid true/false, and algorithm tracing
Output questions test genuine understanding of traversal and complexity
Covers arrays, lists, stacks, queues, trees, heaps, graphs, and hashing
Live competition makes interview revision genuinely engaging
Run it live in class or send it as an async assignment

Frequently Asked Questions

The quiz covers arrays, linked lists, stacks, queues, hash tables, trees (BST, balanced, tries), heaps, graphs, sorting and searching algorithms, recursion, and time and space complexity (Big-O).

Quiz mode asks multiple-choice concept questions. True/False mode runs fast fact-checks for quick participation. Output mode presents an algorithm or snippet and asks players to trace it and predict the result or final state.

Yes. It targets the exact data-structure, complexity, and algorithm-tracing knowledge that coding interviews assess, making it effective for individual and group interview prep.

Yes. It is designed for group sessions. A class or club joins one room, competes live, and the host gets a topic-level breakdown of where understanding is strong or weak.

Yes. Hosts can send any mode as an async assignment. Students complete it on their own schedule and results are recorded in the analytics dashboard.

Yes. The MCQ and output-prediction rounds mirror the technical screening round used in campus placements, so students can practise recall under time pressure. Hosts can run it as a group mock test for a whole batch at once.

Yes. Build a question bank from your syllabus, assign it to a group, and run live revision rounds before the exam. Results stay in the dashboard so you can see which topics the batch is weakest on.

MindLoop is a free alternative that bundles DSA quiz rounds with question banks, assignments and long-term analytics in one place. Where Kahoot and Quizizz focus on one-off quiz rounds, MindLoop keeps a persistent workspace for your school, college batch or team, so progress carries across sessions instead of resetting every time.
