LeetCode is the best platform to help people practice solving coding problems and prepare for technical interviews. The main users are software engineers. LeetCode has over 1,900 questions covering many different programming concepts.
Scratch might be a bit more popular than LeetCode. We know about 578 links to it since March 2021 and only 544 links to LeetCode. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
General Coding Assessment (GCA): the harder of the two, but manageable with preparation. It's done on CodeSignal, either in person or online. To prepare, practice DSA questions on competitive programming sites like LeetCode, Codewars, and CodeChef for 1–2 weeks, and you should be in good shape. - Source: dev.to / 25 days ago

Plain BST. Fine when input is random or the problem doesn't require worst-case guarantees. Tree problems on LeetCode typically assume balanced input and don't ask you to maintain balance yourself. - Source: dev.to / 4 months ago
Your preparation should not be random. Platforms like LeetCode, Codeforces, and GeeksforGeeks are tools—but what matters is how you use them. - Source: dev.to / 4 months ago

What I wonder is: why has nobody noticed that code editors lack a concept of 0? When you're writing code, you can express any concept except that of an unfilled hole. We've rearranged every part of the coding process in a twisted-up way, all for the lack of a way to express lack. If you want to be more clear about what I mean, look to tools which can express holes like https://scratch.mit.edu and https://hazel.org. - Source: Hacker News / 7 days ago

The average house in the UK now has 1.3 laptops. https://www.theguardian.com/technology/2015/apr/09/online-all-the-time-average-british-household-owns-74-internet-devices A windows laptop from today is vastly easier to code on that a C64 or whatever. Most houses would have an internet connection as well so they can get to all sorts of things. A Raspberry Pi is probably something richer kids get to play with. Have... - Source: Hacker News / 3 months ago

My 2c from lots of remote math tutoring, and one coding-for-fun middle school student: - student motivation is everything. Hard to motivate thru a screen and with cameras off. Hard to keep them engaged or recognize if they're engaged. Less of an issue with adult students. - reduce friction for students as much as possible. Ideally one web tool, zero installs. Prefer tools with few failure modes, and have fallbacks... - Source: Hacker News / 7 months ago
