This is excellent, very nicely done, thanks so much for your help that cleared it all up!

Could someone please explain what ~~ is, I can't find anything on it.

Also what is the c = c > 9 being used for?

Great explanation, trying to learn regex as well, could you explain '$1 ' as well? I've seen some explanations but I am not fully sure how to interpret and your prior explanation cleared things up for the first part of the statement. Thanks!

Thank you mojodev for your response. I actually do understand everything except the replace code. I know what replace does as well but I want to know how do we write the code for the

"last instance of 2 things being seperated by a comma and replaces it with a '&'"

I don't know what .* or $/ or $1 &$2 does? Would you have a resource for how you learned that text? Thanks!

could you explain the replace code or give a resource where to learn, I don't understand it all :)

meaning the actual code in the replace method, I know what the method does just don't understand how you are identifying what to replace and also don't understasnd $1
