BIG O(n) BABY. LETS GO!!!!!!!!!!!!!!!

low amount of lines but time complexity higher than mine :P

Even tho you most likely won't see this, but hate to break it to you - not everyone cares about coding principles - if you can do something in one line of code and it is not very unreadable, a lot of people will do just that and most people are fine with that.
In production and development codebases for huge apps - of course its better to keep things simple and readable, but if you can condense two or three loops to just 1-2 lines, but then explain the choice in documentation - thats way better.

g for global, which is used for pattern literals right?
and i for CASE-iNSENSETIVE?

This is literally me when I started coding.

wow bit shifting so clever

if you are wondering why i calculate some abstract "len", its cause i am sleep deprived RIGHT NOW, but you know...
C AIN'T WAITING

The String.split(String s) splits the string into an array of strings in places where there is s in the original string. So you have something like "hello world!", and if you do "hello world!".split(" ") it will split the string into an array like this:{"hello", "world!"}
Then with the [0] he is accessing the first element of the array. 0 is the first element in Java and you access array elements by an index with square brackets, remember!

Thanks for your explanation.

I saw the comment, but I forgot the size is specified in the declaration, so I basically was like "you give me an array, but the memory is not allocated yet", which is wrong, thanks!

I am doing codewars fundamentals only right now, in between reading "The C Programming Language", and I am only on chapter 2, so yeah I know nothing about how all this stuff works.

bruh. its not specified so i calculated the size and allocted that much with malloc

are you dynamically adding more space to the array with the *integers++?

Glanced over, and yes its the same algorithm. Yet it still looks better than my stuff lol

I had to implement addition by columns like in first grade, you know? For this to work...

Is this code the same type of thinking or what? Cause I don't feel like looking up libs you used
