Rewrite a for loop using recursion
Level: Beginner (score: 2)
Although you have to be careful using recursion it is one of those concepts you want to at least understand. It's also commonly used in coding interviews :)
In this beginner Bite we let you rewrite a simple countdown for loop using recursion. See countdown_for below, it produces the following output:
$ python countdown.py 10 9 8 7 6 5 4 3 2 1 time is up
You will be tested on having the same output, making it work with another start value, and of course if you used recursion. Have fun!
