Build your coding interview instincts, one short session at a time. Hourly DSA helps you practice data structures and algorithms in the spare moments of your day. Answer focused questions, recognize the right approach, and understand why it works. MAKE EVERY BREAK COUNT Work through a five-question daily set or choose a topic to practice. Short prompts and tap-to-answer choices make it easy to fit a little interview prep between classes, meetings, or whatever comes next. LEARN TO SPOT THE PATTERN Practice the clues that point to a hash map, two pointers, sliding window, binary search, and more. Build the habit of asking: which approach fits this problem, and why? THINK THROUGH THE CODE Predict the output of short snippets, reason about time and space complexity, and catch common misconceptions. Focus on the thinking behind a solution with compact questions you can work through on your phone. UNDERSTAND EACH ANSWER Get immediate feedback and a concise explanation after every question. See the key idea while your reasoning is still fresh. KEEP PRACTICE IN SIGHT Add widgets to your Home Screen or Lock Screen to keep questions, interview patterns, and your streak close at hand. BUILD A DAILY HABIT Track your practice and day streak as you return for another short session. Explore foundational, core, and advanced topics at your own pace. TOPICS INCLUDE Arrays and hash maps, two pointers, sliding window, stacks, binary search, linked lists, trees, heaps, backtracking, graphs, and dynamic programming. Whether you're studying computer science, preparing for a software engineering interview, or refreshing the fundamentals, make room for a little DSA every day.
