Ok I get it now, thanks for the heads up

Yeah sorry I did fixed the comment right after I posted it with the language I'm using at the top!

Not sure I understood what you mean, returning the same list where?

Ok thanks! Im quite new here and was the first question, I wasnt even sure what I wanted to ask!

I was using wrongly the function String.IndexOf, I was getting the same number if there were two equal digits and the Pow function I made was spitting out random numbers! I figured it out at the end, thanks anyway!

p.s. I forget everyone is using a different code! I'll keep that in mind

my code works just fine with normal tests, but with random tests my final array only gets to 1306? looks like it cant workout higher numbers
