this is a good problem
damn man!!! i just tore my head off to solve this then i figured there is a very very simple way to do that
A simple yet good problem. It made me think outside of using if and for loop.
This problem made me think and force me drop my all weapons(predefined function ) even for loop ,and while loop
Thanks for showing how to check for loops and other unwanted commands in the function. This is really helpful to test my students.
