I told everyone I was going to stay up and do my assignment... and so I did. It involved checking for permutation pairs of digits where the second digit is 8/5 of the first.
I'm not going to put code online because that's a 100% sure way of having someone steal it so I'll put a printout of my program here so other people can check me but not be able to get any ideas on how to solve the problem
I think you will all find that I have a correct solution, please point out a mistake if you find one. At the moment there is one place where I can increase efficency if I work out how to quickly find the length of a number, (i.e. 1234567 is 7 digits long). My entire assignment being 12 actual lines of code long (that's with extra line-breaks to improve readability).
I have also started writing a summary of the course for my revision before the final exam. If only I could be this efficient without buying a dozen energy drinks.
