Recursion is a very important tool in programming. It is also difficult to understand. In this post, I want to show an example of a problem that can be solved with recursion and will help you understand how to use backtracking. Backtracking is a useful technique we can use to verify all the possible solutions

Do you want to learn algorithms in programming? Are you wondering where to start? In the next paragraph, I give you the answer. The study of algorithms in programming has two main topics: algorithm analysis and algorithms design. The recommended way to learn algorithms in programming is to start learning algorithm analysis. Only after that,
