This is very similar to my solution great thinking!

Maybe you're right.
But as for Java kata, it doesn't worth even 9 kyu :-)

I'm relatively new to C++ katas. I dont have a negative opinion on the point values. it's all good practice in my book

it is okay to use external header files for solving these katas correct? I haven't programmed in C++ in some time.

Please be more specific. If you think the description is inadequste, suggest a better one. If you can't pass the tests, post your code, properly marked up and spoilered, post a failing test, input, actual and expected output, and mark it Question. ( Mention the language. You did that right. )

Closing.

Not a kata issue then. Closing.

Is there even anything like java.regex?

What would you need anything from cstring for? I don't think it's necessary, but maybe you have some good reason to use it?

does anyone thing using <cstring> would be incorrect for this kata?

Press the "Reset" button, and the tests should reappear.
Save any code that you might have before you do this.

Does anyone have the Sample Tests for this Kata? I seem to have deleted them by mistake
