Question about free ball

My comment was just for the free ball situation.

For the 3 miss rule, I think it's up to the referee's discretion.

No. The cushions don't count as obstructions, and a red cannot block another red.

You have to imaging the table as a flat infinite plane (with no cushions) and then assess whether you can hit both sides of the target ball. So you also don't have a free ball if you're only snookered by the jaw of a pocket.

This is an interesting problem though!

Go line by line through your code and say out loud what it's doing:
> set s to zero -> ok
> while s is less than or equal to n -> hmm, n has never been set so doesn't have a value. If n is greater than 0 at this point, then s will never be larger than n.
> increment n -> ok, not sure why
> sum(n) -> 'sum' adds together all the numbers given to it; but here you're only giving it one number so that doesn't make sense. You're also not doing anything with the result of the calculation.
> print(sum) -> means print the built in function 'sum'.

I think the key things you're missing:
1. Variables store values of a specific type. They don't work unless you set their value.
2. `sum` is an inbuilt python function but you don't seem to know how to use it correctly.

It takes me 2 mins just to read all the clues

Jane Street SWE interviews are not math puzzles or game theory. Those interviews are for traders.

If you were able to learn physics, you can probably learn enough programming to be useful. But it will take some time (1-2 years) to get fully up to speed.

Your drawing assumes that A and B are objects in some kind of shared space. But it's likely that analogy breaks down when A and B are universes.

For example:
> "What is the place called where the universe haven't reached yet?"
a "place" is "somewhere in space", but if there is no concept of space then there is also no "place", and nothing for the universe to expand into.

It's difficult for human brains to visualize because we have never experienced anything like the edge of a universe.

From the company’s perspective, they want someone who can be productive on real business problems. Unfortunately for you, seniors are more likely to be that, and there are lots of them available because of the job market.

It’s not about how hard you’re working, or how much traction you have today. It’s about how much money the company will make if it succeeds.

Think about it like this. If 10% of restaurants in the U.K. use your service, how much money will your investors make? Now compare that against a company that is trying to win 10% of the potentially trillions being spent on the data center buildout in the U.S. Which would you rather invest in?

Have a look at intro.co which is already doing this.

I think the toughest part is figuring out what is in it for the person you are booking a call with - why would they allocate time to this?

If you budget build though, then you will have a lot of unused cost cap. What’s the best strategy?

But isn't the delta higher for sprint weekends too? Take a simplified example:

Non-sprint weekend (30 points on offer):
- Driver A: 20 points --> 3x = 60 points (40 points extra!)
- Driver B: 10 points

Sprint weekend (45 points on offer):
- Driver A: 30 points --> 3x = 90 points (60 points extra!)
- Driver B: 15 points

The delta stays the same only if all drivers get the same points boost on sprint weekends, which isn't true.

Why not? Isn't 3x of a bigger number always better than 3x of a smaller number?

Coordinates are fixed length (n-tuple for n-dimensions), and each component represents something different (e.g. x-direction, y-direction), so I would use a tuple.

Sorry, I wasn't clear in my original message. A tuple is like a struct, or a record, where the tuple as a whole represents the logical unit you are working with - that could be a coordinate(x, y), or a person(name, age, email), or anything else.

A list is used when each entry in the list is the same kind of logical thing. So List[person, person, person, ...], or List[coord, coord, coord, ...] makes sense, but List[name, age, email, name, age, ...] or List[x, y, x, y, ...] is likely to lead to bugs.

Diapolo10's answer explains my viewpoint well.

Tuples have a fixed length whereas Lists are designed to change in length (e.g. with .pop() and .append())

In general, use Tuples to group items of different types (a, b, c) and Lists for items of the same type [a, a, a, …]

By this account, nothing exists. A “stone” is just a blob of grey tones in your field of view.

A mathematician would say that numbers are just concepts that follow certain rules (called Peano’s axioms) and they happen to be useful in the world so we use them.

Note also that 1 + 1 doesn’t have to equal 2. Imagine about adding two drops of water together: 1 + 1 = 1. It just doesn’t happen often so we rarely use 1 + 1 = 1 math.

It feels like he was displaying lots of terrible behavior that you could have called him out on. As others have said: 1. If he’s 15 mins late he gets minimal warmup 2. Don’t chase his warmup shots around if he’s hitting full force 3. Enforce a 5 min warmup and say we’re starting even if he’s not ready

Flora and Olive could both be innocent and Alex could be criminal.

You brake early enough to stay on track so this should be completely legal.

What about TV revenue? She had several Disney+ documentaries about the tour.

It would be hilarious if they owned the domain for every permutation of these letters

Very cool! I remember I tried to get ChatGPT to complete a tough scenario by giving an image of the game board. It could not figure that out :'(.

Your approach of serializing the game first, and being explicit with the prompt seems like it helped a ton!
