This is the solution that helped me understand it. Thanks!

Hey! Quick heads-up about using indexOf in Java:

Even if your tests pass, using indexOf("word") > 0 misses the case when the word starts right at index 0 (the very beginning of the string). That’s because indexOf returns 0 when it’s at the start, and 0 > 0 is false.

To correctly detect the substring anywhere (including at the start), you should check:

(s.indexOf("word") != -1)

I apologize, I didn't know

What is a use of the first argument, int n? Its not needed, i believe.

Fixed a long time ago here

Edit: my bad, the translation was rejected altough there is a comment saying it got approved under it's suggestion. Reraising.

Use enumerate, dude

My solution is easier to understand. This was a lot like Fizzbuzz.

this is super slow...

My friend, we write solutions not tests. The TESTS round answers, not solutions. What are you talking about?

Very complex problem to figure out not only from the description, also the performance requirements are pretty high for being only a 6th kyu.

good
