cool!! im a junior dev looking for that solution! thnx

@georgekakarlis If you know what modulo operator does, you can do it in your head or on paper. Which I did and I just got curious how it would look like in Go. Mostly, because the original ad has no type casting from string to integer and I wanted to do something fun this morning. Turned out I don't know type casting well in Go :D
