Recursion (computer Science) - Order of Execution

Order of Execution

In a recursive function, the position in which additional statements (i.e., statements other than the recursive call itself) are placed is important. In the simple case of a function calling itself only once, a statement placed before the recursive call will be executed first in the outermost stack frame, while a statement placed after the recursive call will be executed first in the innermost stack frame. Consider this example:
