of course they are. The Chinese team selection tests are notoriously more difficult than the IMO, and they enforce a one-time participation limit. If they were to send 24 people, not only would they probably be returning with ~20 golds, the

Yeah, that was a very weird comparison. Not only do those countries send 6 people each, those four started participating in 1959 while US started in 1974 and China in 1985. Though arguably, those first olympiads featured fewer countries, (w

There's gotta be something between Satya and "C-tier code out of rural India". There are of course lots of bad coders in India, but there are also many really good ones. And whereas in the past they had to emigrate to US or E

I believe what GP is saying is: coming from python, which uses `and` and `not` and `or` you expect those to be the binary operators in ruby as well. You are then surprised when they behave unexpectedly. Who is then to blame for your frustra

Kotlin is very ruby-like and performant, check it out. If you don't mind using JetBrains IDEs, I'd give kotlin a try.

`and`, `or`, `not` have much lower precedence than `&&`, `||` and `!` . I would just avoid `and` and `or` in general. For some more explanation see https://graceful.dev/courses/the-freebies/modules/rub

Or it could be a typo (as in man-made) My guess is that they only use Youtube videos that already have subtitles in the target language. But I'm curious to know how exactly they've built their database of videos/transcripts.

Thanks for the reply and for the screenshots. before writing my initial reply, I went back and tried to get a 50/50 split based on your comment and came up with the same solution. But I didn't understand why it worked. I now belie

Can you explain more? (I might be stupid and don't see some obvious proof of why your approach is correct), but intuitively it doesn't seem that the fact that the cup is symmetrical is enough. Say if the handle of the cup was real

ruby is strongly typed, in that it doesn't allow you to implicitly coerce between types*: 1 + "1" will raise an error. (As opposed to weak typing in C or JS) ruby however is not statically typed. *(there are actually ways to

Leetcode is fine: lots of supported languages, large community, lots of solutions and editorials. Here are some more resources: - USACO: https://train.usaco.org/ and https://usaco.guide/general/ - Code

Great resource, but it's hard to practice there as a beginner because there are no solutions (unless you solve the problem yourself). So you might have to get comfortable with being stuck. Which is fine when you're experienced, bu

their relationship is more complicated. Some might argue Putin is Karydov's b**h, seeing as how the federal government is paying large amounts of money to keep formal control over Chechnya and Kadyrov's clan happy.
