This simple program tests if a number follows the Collatz conjecture. The numbers may only be natural numbers (positive non-zero integers). The scratch cat saying "finished" means that the number follows the conjecture. If it says "found," make sure that your input was a natural number. To try a new number, restart the program.
Thank you to Tipping Point Math, whose video on the conjecture I watched. https://www.youtube.com/watch?v=m4CjXk_b8zo
