he is using list indexing, ['Underweight', 'Normal', 'Overweight', 'Obese'][0-3].
if you want to know in detail i suggest asking gpt

thank your for the comments. I was so lost looking at people's solutions

ooooooo! I'm so happy. It's the second Kata i solved by myself.

can someone tell me what method this is? This is my first times seeing it

quick question! how does it not give the error when we use result without initializing it?

this is the first kata i did on my own. It's pretty easy as the answer is literally in the question but ahhh

See of this helps: https://docs.codewars.com/training/troubleshooting#timeout

i'm actually gonna cry what is this. i feel like i get it but at the same time i don't😭

why is my kata not being submitted? it loads for a while and gives this error Execution Timed Out (12000 ms)
