How do I understand tough tough looking algorithms like this?

I am really afraid of this algorithm. I don't understand a single word.

here is the doc of that pdf.

both links are same pdf.

I understand bfs via other algorithm. but this looks so scary man...I am feeling imposter syndrome after seeing this, I basically know nth written in algorithm and how it works?

 

I suggest you try
https://github.com/search?q=to+understand+bfs
and ask the question, none of us here is expert in programing

 

What level of math is this question?

 

it's programing question

 

You mean computer programming, right?

 

yeah cs is math imo...

 

ok bro i will stop asking programming qns here

 

Ok. Thanks.
