I never knew this technique can turn a string into an array. We learn everyday.

Awesome! I understand now. Thank you all.

Why does the bounce parameter even matter at all in this equation. Since the boy threw the ball from 'h' that means the initial height of the ball is the value of 'h'.

Subtract bounce from height?

Helps him put multiple statments on same line. Not the best practice.

That means the heigth of the first bounce is 0.66?

So what is the value of -x be?

Never mind, I checked the question again.

I cannot remember touching. Thank you for your feedback.

My solution works when I submitted it but wouldn't work when I press the test button. Why is that?

I always think of regex first. Unfortunately I still haven't master regex. I forget the rules and syntax very easily.

You can't intimidate me. My solution too is great. 😭
