Deduce from the examples what has to be done in this exercise. Find a solution using a function/action which is RECURSIVE and writes to the output. It is allowed that the function/action uses loops, but the solution to the general problem must be RECURSIVE.

Input

The input in this exercise consists of several cases. Each case consists of a positive natural in one line.

Output

For each case, a recursive sequence is written at the output, followed by a blank line. Pay attention to the examples to deduce what the output is as a function of the input.
