Recursion (with Common Interview Questions)

Recursion in programming is important as it provides more elegant solutions which makes the algorithm easier to read than the iteration. But a lot of engineers are having difficulties to understand how the recursion works. In this article, I will dive into it with many examples by showing how it actually works in the call stack. At the end of this article, you will have a much better idea of recursion and how it actually works.To begin with, let’s talk about the formal definition of recursion.
