this wont work with 0 thus the condition 1 2 3 should be only true

I am an enemy to REGEX lol

This must be the best one, it might not be a one-liner, but it is clever and readable. Even if you don't understand it at first glance, it's structure hints at its logic.

I think it's brilliant how you found the pattern to abstract into a general process. But, I would not like to be the one to maintain code like this.

How did this pass the tests though? xD

Nice one!

Perfect!

Subtracting a size_t from a size_t is not well-defined when the result is negative. You should compare them first to ensure that the result is positive before subtracting them. Also, the use of the ternary operator here is just not necessary.

On a real note, how does this work?

Where did you find this character?!

OMG. I was trying the same thing but thought that such a character did not exist!

calm down man

is that not case sencitive? how do you do that?
