Why do I forget about regex?

Learning is life long process and learning is frustrating for one who do not love his work. It totally depends on us what is it we love to do.

If I do coding for money, job, status, etc but do not love it then frustration is natural.

Search a topic called TOC (Theory of computation)

The "," command takes 1 byte from input and puts at the data pointer. So, if we have "Code" input the code ",." will output 'C'. The ",,." should return 'o'. Atleas it is as I understood the assignment.

I was so close...

wow! almost cried after understanding this

Is it work for capital Vowel letters..?

It depends with what part causes you troubles: do you have a problem understanding how Brainfuck is about and how its interpreter works, or you have problems with implementing it in C++?

In any case, you can visit Codewars Discord and its #help-solve or #cpp channels.

Could anyone please point me (pun not intended) in the right direction? What sort of material and topics do I need to learn before being able to solve this? (C++)

Very clever!

Need to be careful with nested brack.

I came back to this kata after 4 years

Amazing

this shit was at the same time the worst and the better problem I ever solved

Haha, I did the same and through breaking down my code line by line on CGPT it was mentioned the code actually evaluates to the last value 'u' due to the way the comma operator works in JavaScript but I didn't bother to do an array like you did.

Simple, yet efficient. I like!
