For CS, you'll have a headstart if you have a bit of experience with Python and problem-solving. Search around for basic material on Python and if you have the time, attempt some problems on https://dmoj.ca/. Source: 11 months ago
Dmoj.ca ! It's meant more so for competitive coding but some of the problem sets they have fall under the Cryptography category. Source: 12 months ago
The first type of practice is general problem solving. This is where you build up a strong intuition of problem and develop general problem solving techniques (but not memorising a huge list of techniques). Of course, the only way to improve is to do lots of problems / contests. For those who are more interested in competitive programming, I really like dmoj.ca (they host contests there as well, sometimes I author... Source: over 1 year ago
Personally, I’ve heard good stuff about DMOJ https://dmoj.ca/ Hope it helps :). Source: over 1 year ago
Sign up for an account on dmoj.ca or similiar online judge website and do the problems there. They have ccc problems and waaay more that you can get your solutions judged instantly. Source: almost 2 years ago
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 / 5 months ago
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: 5 months ago
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: 10 months ago
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: 11 months ago
There is a website called codewars.com where you can select problems of varying difficulty for the language you need. It is very helpful for learning. Source: 11 months ago
