Issue [C++]: use "std::string" instead of just "string" in your code when declaring parameters for the function, otherwise compile error.

C# tests are missing:
"
using System;
using NUnit.Framework;
"

Hi,
--- C# ---
What is the purpose of "public string ballType { get; set; }" - why is it necessary at all ?

Once I got rid of it and just wrote my field and 2 constructors it worked fine;
However, I would like to know the purpose. Is the above some sort of standard ?

(click "View Solution" to see my code)

Hint: Are you using float values in your formulae ?
Instead of writing 1 or 2 for constants, try using 1.0 or 2.0 (python infers the value as float with no need to do float(x); I do not know which language you are using)

I began a journey to find out how to write a function that would calculate an arccos for me, and then i found this in the python docs "math.acos(x)".
I should really RTFM more often...

This is "Kata Suggestions" area of the Forum, you can select areas of the forum on the left.

No one in particular, but thanks.

I've leveled up,
Finally used that lambda thingy.

While your suggestion is positive and welcome, a little grasshopper can be 8kyu, I see nothing wrong with that.

It might be that you have come across a complicated 8kyu kata by accident.
As a mentor, your task would be then, to find the easy 8kyu katas, or, really, create a chain of your own.

Thanks for reassurance,
I was thinking along these lines, but was seeing upvotes mostly on oneliners, therefore was a bit confused.

Thanks to MMMAAANNN for mentoring.
My first python one-liner (kinda)

I'm not criticising though, because your code works, it covers the business requirement ;)
Just a food for thought.

Put the ID of your friend directly in URL and fire away.
I've found a few contacts using their github ID.

P.S.
+1 to your suggestion of course, I've seen similar to those a plenty though. Try to find existing one and upvote it.

Right,
Went through them,
I'll have to think about Python in a more functional programming way.
Really nicely explained, I will try solving something with this approach.

Cool stuff man, I'll go through these 1 by 1
