(pseudo)code cannot be validated if the (input)requirements are not clear.

So, sorry if I took the fun part out of your assignment, but this is how I try to make sense of pseudo-code.

What pseudo-code also doesn't clearly define is the output-format and validation of input. Also things to think about (also in pseudo-code).

As I personally "do" a lot of perl, I think perl, so my pseudo-code *is* perl. Be it with typoes and syntax errors, but perl (when using strict and warnings) will point me at those for me to fix.
