I'm a second-year student from a non-computer-science background, and I'm planning to enter my school's programming competition in about two or three months. I'll have to balance preparation…
I'm a second-year student outside of computer science, and I've decided to try out for my school's programming competition. The event is in roughly two or three months,…
I'm learning my first programming language and want to become better at understanding problems, building logic, and figuring out solutions independently. What single piece of advice would you…
I'm learning my first programming language and want to become better at understanding problems, building logic, and turning ideas into working programs. If you could give one important…
I'm a rising ninth-grade student in Vietnam and have recently started learning C++ with VS Code and an introductory video course. My goal is to pass next year's…
I'm a rising ninth-grade student in Vietnam and recently started learning C++ from scratch in VS Code using the Bro Code beginner course. My main goal is to…
I want to study data structures and algorithms to understand how they work, not just memorize patterns for interviews. My goal is to build a strong foundation, become…
I want to learn data structures and algorithms deeply enough to understand how they work, rather than simply memorizing solutions for technical interviews. My goal is to build…
I'm interested in data structures and algorithms for their own sake, not just for job interviews. Interview preparation would be a useful side benefit, but I don't want…
I want to learn data structures and algorithms for more than just job interviews. The subject genuinely interests me, and although interview preparation would be a useful benefit,…
I'm a student who has started practicing data structures and algorithms in Python. I've solved around 30 coding problems so far, mostly on LeetCode, but I haven't participated…

My solution passes every example and test case I can think of, but the judge reports a failure on a hidden case with no further explanation. I tend…
I'm a university student studying computer science or IT, but my program hasn't covered data structures and algorithms very thoroughly. I want to seriously improve my problem-solving skills…
I've been coding and doing competitive programming and algorithm practice for about a year and a half. I used to really enjoy it, but lately I've started feeling…
I'm a university student studying computer science or IT, but my program hasn't given me a strong foundation in data structures and algorithms. I want to train seriously…
I've loved coding, competitive programming, and algorithm challenges for about a year and a half. Lately, though, I've started feeling like coding is awful and that I'll never…
I'm confused about why this solution exceeds the two-second limit. The grid size is at most N = 2000, and there can be up to U = 100000…
I have an N×N grid containing '.' and '#'. Cells that are rotations or reflections of one another form groups of up to four positions, and I need…
I'm confused about why this solution exceeds the two-second limit. The grid size N is at most 2000, and there can be up to 100,000 updates. I estimated…
