  • Of recursion and backtracking
    Recently, I was working on a coding kata on codewars.com. Early on, I started thinking that a potential solution might utilize recursion, a concept that involves a function calling itself. However, I quickly realized that my grasp of recursion was not as solid as it needed to be for this task. In this post, I will share the insights gained from deepening my understanding of recursion while working through the kata. - Source: dev.to / over 1 year ago
  • 4th year, about to fail an entire semester's worth of classes.
    Get more involved. Look into internships and junior SWE positions to get a sample of what you'd be applying for once you graduate. Solve coding challenges, start working on a portfolio of your personal works. I recommend codewars.com for coding challenges, it's fun. Source: over 1 year ago
  • Beginner with C++ looking for direction
    I'd recommend to play around with some basic coding challenges on leetcode.com or codewars.com. If the course prepared you well you won't find this useful, but playing around with them will make sure that you are comfortable with basics such as loops, if statements etc. Source: almost 2 years ago
  • Can you guys recommend an efficient way to learn in advance IT para sa mga walang alam?
    I would advise for you to start with Python, it's a beginner-friendly programming language and it'll help with wrapping your mind around things. Play around with it, perhaps do some katas on CodeWars and you'll be set. Source: almost 2 years ago
  • How do I develop programming logic?

  • Core Python developer suspended for three months
    Before Timsort, I knew of Tim some 20 years ago from the ranking and online forum of SPOJ[1], a Polish competitive programming website where he always seemed to top the speed leaderboards with unorthodox usage of Python. He's exceptionally talented and original, and that sort of nonsense doesn't go well with a bureaucracy. [1] https://spoj.com. - Source: Hacker News / 9 months ago
  • Entrance Test for a school!
    Have you looked at spoj.com? It has a fair amount of different problems, some of them are pretty creative, you can take an inspiration from that. Source: about 4 years ago
