Here, We will learn about recursion, iteration, differences between recursion and iteration and their code in java. Recursion Recursion is a technique in which function calls itself until a base condition is satisfied. A recursive method solves a problem by calling a copy of itself to work on a smaller problem Example Recursion Code in
