Any recursive algorithm is convertible into a non-recursive one...
and vice-versa!
The cost may be a great difficulty, a loss of simplicity, a loss
of efficiency.

Such a simple search that I tried just before you was born!

Not to all people, only to all who:
- didn't understand the question
- doesn't have an idea about the solution.
- doesn't hesitate to spend unuseful words... as it costs nothing!
