About this app

Build stronger coding interview intuition with StepCode, an active practice app for Data Structures and Algorithms.

Instead of only reading solutions or memorizing code, reconstruct the logic yourself. Arrange algorithm steps in the correct order, identify misleading decoy steps, use hints when you need them, and learn to recognize the patterns behind common technical interview problems.

StepCode helps you turn scattered problem-solving knowledge into clear, repeatable thinking.

WHY STEPCode?

• Active recall practice: Rebuild algorithm solutions step by step instead of passively reading explanations.
• Interactive DSA puzzles: Assemble the correct sequence of actions and test your understanding immediately.
• Decoy steps: Learn to distinguish essential logic from tempting but incorrect approaches.
• Guided interview paths: Follow structured learning tracks from foundational patterns toward interview readiness.
• Personalised practice: Choose your experience level and focus topics so your practice starts where you need it most.
• Daily goals and streaks: Build a consistent practice habit with progress tracking, daily targets, and earned stars.
• Review reminders: Revisit problems as they become due so important patterns stay fresh.
• Helpful hints: Get progressive guidance without immediately giving away the full solution.
• Difficulty and topic variety: Practice across the patterns and concepts that appear frequently in coding interviews.
• Code references: Review implementation examples in Python and JavaScript after mastering the underlying logic.

PRACTICE IMPORTANT INTERVIEW PATTERNS

Work through topics such as:

• Arrays and strings
• Two pointers
• Sliding window
• Fast and slow pointers
• Binary search
• Stacks and monotonic stacks
• Trees and traversal
• Graph algorithms
• Dynamic programming
• Matrix problems
• Sorting and searching
• System design foundations

A BETTER WAY TO PREPARE

Whether you are building your foundations, actively preparing for interviews, or staying sharp between opportunities, StepCode gives you focused practice that fits into your day.

Use a few minutes to strengthen one pattern. Follow a complete roadmap when you have more time. Track your progress, return to due reviews, and gradually build the confidence to explain how an algorithm works, not just copy its code.

StepCode is designed for:

• Computer science students
• Self-taught developers
• Software engineers preparing for technical interviews
• Developers revisiting core algorithms
• Anyone who wants a more active alternative to passive coding practice

Start with one problem, build the sequence, and code with confidence.
