When we programmers look at the universe, we see it as a big collection of small, resolved problems. The world that is around us is evolving every day, it is getting better and better, although sometimes our efforts give opposite results. Our most important skills in programming are describing functional models in business processes, discovering active entities and the relationship between them in the problem environment, and providing optimal solutions for mapping them in the virtual world. Regardless of the different programming tools and languages, the habit of breaking the problem into smaller parts and presenting the problem-solving processes step by step, is what is called the programming or algorithmic approach in problem solving. I can share my experience with you to learn data structures and algorithms, help you improve your abilities and prepare for job interviews.
