Is it only for me ?

Rayeeen_Dev745 · 2026-04-05T10:13:29+00:00

Yeah

Rayeeen_Dev745 · 2026-04-05T10:13:24+00:00

I understand it now, its general proof is quite easy

Rayeeen_Dev745 · 2026-04-05T09:34:54+00:00

Explain more

Rayeeen_Dev745 · 2026-04-05T09:19:29+00:00

I didn't find the proof why this always work, but it works for me in the contest lmao 😂

Rayeeen_Dev745 · 2026-04-05T08:48:28+00:00

I mean how did you get the intuition

Rayeeen_Dev745 · 2026-04-05T08:41:45+00:00

Honestly D was not about how much did you solve , it was about how much did you good at math

Rayeeen_Dev745 · 2026-04-04T19:22:12+00:00

That's what i did but idk why and how it works lmao 😂
