  • I'm trying to figure out what language to learn to grasp the software engineering concept
    This is also why many people will suggest you find a project. As it will start you programming somethin and very often something you have some kind of passion or need for. But if you cannot think of a project to do, then I would look for guided projects or programming gamified like kattis.com or leetcode.com. I would highly suggest you do not watch tutorials without coding anything, as this is almost always wasted... Source: 5 months ago
  • Stuck in my progress.
    Have you been on https://kattis.com? It’s full of C++ practice exercises that you can sort by level of difficulty and run through tests to check. My teacher had us use it for practice. Hope it helps! Source: over 1 year ago

  • [2023 Day 8 (Part 2)] Some notes on features of input data
    Have you heard of codeforces.com, atcoder.jp, codechef.com, etc? Source: 5 months ago
  • How helpful is leetcode at competitive programming?
    Leetcode is good to learn basic algorithms because problem statements are usually straightforward. Competitive programming has much wider range of problems. Most popular sites for cp are codeforces.com , atcoder.jp, codechef.com . Source: 5 months ago
  • Role of Algorithms
    The de facto standard community for competitive programmers, regular contests with editorials, huge archive of problems (https://codeforces.com/problemset) with pretty accurate difficulty ratings so you can focus on problems of suitable difficulty if you want to progress quickly. They also have an incipient EDU section: https://codeforces.com/edu/courses that covers basic algorithms with practice problems. - Source: Hacker News / 7 months ago
  • I just graduated with a CS degree. I want to start my career. What do I do?
    - I used C++ to solve 500+ problems on codeforces.com (a competitive programming website) But I'm rusty now. Source: 9 months ago
  • What to do after learning c++ basic?
    Join the codeforces.com cult try out some most solved problems and then there are many other things like cses problemset, a2oj ladders... Just a tip learn c++ stl too (not necessarily now but do it soon). Source: 11 months ago
