Recursion is a technique in which a function can call itself, opening another instance of that function within the current one. The capabilities of iteration and recursion overlap greatly, but in many cases, a recursive solution is significantly cleaner and more efficient. Recursive solutions excel over iterative ones when the target objective involves a task with arbitrary dimensionality. The general construction of a recursive function consists of a base case and a recursive case. While the concept may seem simple, the execution is not! Many novice programmers struggle to grasp recursion. Make today the day you master recursion!
