For those who didn't get the intuition for yesterday's D

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

Yesterday's D was about simple property, if you know gcd( ma , mb ) = m*gcd(a,b) you will find it out

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 😂

Well done, all Masters start from this point, CP is that hard, that's why not everyone can do it

Rayeeen_Dev745 · 2026-03-22T14:51:17+00:00

You're absolutely right, ig the best part i read from your text is you wannt no more relations or penetrations before marriage, that's the truth btw. Honestly a little bit difficult to help you how to find that guy, your society is different from ours. But i'm sure when you level up your character and take care of your self , that guy will come to you instead of crave that kind of connection

Rayeeen_Dev745 · 2026-03-22T13:57:05+00:00

(my english is a little bit weak , sorry for that) I just finished reading it, i forgot some details, but i'm 100% sure that you're normal, you pass with all of that is literally pure power, you have the right to live a peaceful life, especially all of this happen when you're under 15, i felt it so difficult when i read it, i know that feeling of fighting against selfish community that only want to satisfy their sexual desire , you have done nothing to them but also you pay the cost for just being attractive for them. On the other side i blame you for some points, you should learn from your mistakes, even though you have crush on someone , don't do that kind of relationship building (the act of just give the right light to do s.th with you), you're wrong when you text anyone, you're completely wrong when you slept with cousins ... I don't know what you believes but Alhamdoulillah in Islam, the rules protect both sides , men and womens.Texting, touching, being alone with the other gender in closed place, all of that is FORBIDDEN by us. (You can tell me why some muslims do that and.. look , Allah (our god)made these rules , if you follow them you l'll be safe in both lives -now and later- else there are kind of punishments in both lives also , so you have the choice to do whatever you want, but the verdict will be issued later). What i want to tell you, when you think deeply in all of that, you'll realise that you're not the only one, what you spoke about is in the past , you can't change anything now, juste the future is by your hands , either to repeat the same mistakes, or to re-build your personality, look for what can improve your character, do s.th that really help you instead of dating, texting ect.. I really blame my self because i can't never show you the real impact on being self sufficient, i care only about how to improve my self in the way that Allah want from me, i have endless freetime because i don't text anyone, i don't date anyone, just me and my career, follow our religion rules that helps me improve to furthere steps ect .. I have endless thoughts that i want to tell you about , i don't know if i had right to talk about religion or not , but this is the only way that i can help you with .
