I am currently on a gap year, and I intend to learn a programming language on my own. I know single variable calculus, some basic probability, statistics, and combinatorics, but absolutely nothing about computer science. I would appreciate it if anyone could help me figure out a good starting...

So I am in my Intro to CS course and they are going over Binary searches via an algorithm to search for simple things. The code goes as this: Set first to 0 Set last to length-1 Set found to FALSE WHILE (first <= last AND NOT found) Set middle to (first+last)/2 IF...

I recently changed my major to physics from business. I would be going into my senior year as a business student had I stayed, so I have all my core requirements done. While I'm catching up on some maths, I'll need to fill my schedule with electives to remain a full-time student. What courses...

Hello all. I am at an impasse with what I want to do with the rest of my life. Academics wise, I have always had an interest in maths and science and history. There is no greater feeling in the world than solving a problem you have been stuck on for hours. I was researching potential degree...

Im fairly inexperienced when it comes to programming. I realized a lot of internships require knowledge of programming. So, my question for you guys is: Since I'm a new master's student, and looking to become more competitive for jobs and internships, what sort of programming courses would prove...

I thought of building a human cyborg where the programming is done like a robot but it has human organs and cells and grows just like a human does. This involves quite a bit of typing for certain organs like the heart. The program says to me in a female voice "Select cyborg" and I select human...
