In this link, I do not understand what for the editor has chosen variables i,j,k,l. Can someone explain me please?

Honestly, reading other people’s code written for Competitive Coding is pretty much always a waste of time (even if the author is Editorialist!)

Case in point: aside from the unhelpful i, j, k and l variables which you’ve noticed, it also introduces a function, helpfully called modulus1, which is absolutely identical to the built-in abs function XD

Oh okay. Never mind, I’m a beginner. Can you also explain the part from the 30th line of the code please?

I’d rather not try to decipher it XD

Is my code helpful to you, at all?

Yeah, thanks. I figured it out.
You seem like a pro,so can you provide some tips to a beginner in Competitive Programmer like me?

I’m afraid the only advice I can give is this
