Thanks for your explanation, it provides a great detail on how the entire system works.
I've attached few resource materials that helped me in understanding the terms, but good
understanding will only come by expirience.

Cool Kata, lot's of learning.

The test are tricky :) , do not overthink.

Could you please let me all the concepts that you have gone through ?
How have you managed to link all the terminologies together like:

• linker cares about is that there is something called multiply associated with a callable piece of code
• is an IEEE754 double number
• (little-endian, hexadecimal notation) what made you think it was little endian was it the assembly code ?
• System V AMD64 ABI that Linux uses how are you associatting these termss with the code ?

can you name the resource materials, concepts that I would need to learn in order to have knowledge like this.

Amazing kata !,

• The description could provide an example with n = 14.
• User needs to understand what happens when control reaches at 'z' based on string index.

good Kata !!

I think the function argument itself provides a hint to solve this problem.

What is that ascii diagram, I'm curious.

In real time production code is this recommneded ? since it's not a part of C standard.

Hmm, arr is a pointer to a const integer, good use of arr here.

It's crazy how people are good in using bitwise operators.
