What kind of tools would you like?

Question

Recently I've been wondering on how I can improve my programming skills, but also to make things easier in my school career.

So I decided to make a periodic table to calculate a molecule's mass, Concentration in a container and I'm looking into calculating the pH levels too.

But there's so many other things that can be done, and so many ideas.

Tools are very important to help you in the programming world. What kind of tools have you made, or like to make?

Answer 1

Solve algorithmic problems. I usually use algo.ubtuit.uz
