 All right guys the content is about to start in one minute. I'm just talking very slowly Cuz I'm very tired So what I'm doing is that I'm gonna start this contest And I'll see if I could solve two problems, and I'm not gonna talk because I'm actually Very tired, and I'm gonna try to do this very fast. So Yeah, did you scratch mine? Okay? Hmm absolutely Yes, okay Budge cakes 11 How do you do this? So low BF is equal to zero. What if I do S plus W is Greater than P then we could do this also This is hurting my head, okay, let's put this over here Budge cakes. This is so hard Okay, so we need to put this at the end Wow, this is very hard Okay I don't think this would work though. Yeah, it didn't work. I guess we'll try to absolve this later The math question is so hard Okay, let's go to the next one actually and You are given an integer x and a resulting string s we construct the original w Maybe I shouldn't have submitted B and push me back down Two three man. I shouldn't have submitted Okay, you're given x you need to be build a string y how you choose it is if I Minus x is equal to one s equal to one i is greater than x Okay, it's equal to one is one if it's plus equal to one Then s of i is equal to one one one one zero one one Pick a letter three one two three There's index from one one zero i minus x It's either length of it This kind of sucks Hmm, how do you do this? How do you do this? I minus x I the character of s is chosen is equal to one Hmm, I don't know Hard hard very hard. It's a very hard problem. I'm like it's off a and B This guy submit anything Pick the ith letter as chosen How do you reconstruct that? Very difficult very difficult very difficult very difficult difficult difficult See this guy is this did this guy get anything? No This was tough. This is tough tough problem Damn, I got pushed back someone submitted something. Huh? You could you could get very high ranking just from submitting it in five minutes That's interesting Figuring out the problem in five minutes. You could actually get very high ranking. Hmm Maybe I should try to solve a very fast next time. This guy's good minus four 30 was 30 this guy's definitely not a newbie. How do you solve D? What's D? Wait Number of two poles. What's the problem after zigzags? Very difficult very difficult. Okay, so I'm gonna give up now Very cop scribe. I'll check you guys later. Peace
