If you want to randomly pick a Codeforces problem to solve based on rating and tags, I made a tool for that. No login required and it won't show problems that you've already solved. Give it a try: cf-random-unsolved.onrender.com
could only solve 2 problems. today's contest is math heavy. D seems doable for me... will try it for a while
Render uptime issue: I have been using an uptime bot to ping my server every 5 minutes which keeps the site alive for up to 24 hours (still better than the usual 15 minutes on free tier). I want to know if there's a better way to keep the site active for a much longer time.
You can actually find test cases on codeforces where your solution fails (except during live contests)
Built a simple C++ code editor for competitive programming (input/output sublime style) Write, run and test your code directly in the browser. check it out: cp-code-editor.onrender.com
I am building a web app where users write C++ code in the browser (Monaco editor) and my backend compiles it with g++. I am moving to Render and need g++ available there. Should I install build essential in the build command or use a Docker file?
struggling with constructive algorithms problems. how to build intuition for constructive problems? any tips? thanks in advance.
sometimes it feels like 900 rated cf problems are actually tougher than 1000-1200 rated problems, rating inaccuracy exists for all rated problems but the ratio of 900 is kinda high imo, though rating also depends on contest and how many people solved particularly so makes sense
done for today, expected worse but sorta good (first DIV3, I could probably solve C if I gave it more time, but I'm skipping it for now)
