@Lyxal yeah, but it's meant to be a portmanteau of cons and curry, with the unintended side effect of sounding like it's going to be concurrent (maybe it will?). Also concur is how you spell it when you use it that way

From this you can determin...

Can anyone (familiar with some JavaScript plotting/interactive library) write a leaderboard snippet for my challenge?

... if I made the leader board snippet, perhaps I should make the answers put the (A, B) values in the header.

Then there are people suggesting improvements in comments, and people updating their answer...

It's hard to get this correct.

Just won a game of Monopoly and now my family hates me because I used like 20 mortgages and took advantage of every tiny detail in the rules

Lyxal

@RedwolfPrograms well they need to get over it

you won by using the rules

You won by knowing the game

And that's a good victory

Redwolf Programs

One of my first major projects with JS was simulating Monopoly to figure out what properties to buy

And a note from our sponsor, "math program I made in 4th grade":

@RedwolfPrograms did you win any games with it

Redwolf Programs

@Razetime No, I just buy everything I land on :p

Razetime

@RedwolfPrograms valid strat tbh

Redwolf Programs

Yeah, usually my family doesn't have time to finish a game so we just add up our cash and property values, so you can't really lose money by buying properties

Razetime

bruhhh

I have finished exactly one monopoly game in my life

rest all were ones where someone just ragequit or it just goes on too long

Redwolf Programs

Monopoly sounds good on paper but the implementation just lets games go on way too long

Plus nobody actually knows the rules

There are so many weird technicalities, and most people I've talked to don't even know about auctions

Razetime

the instruction booklet gets torn to shreds by the time someone actually reads it

the actual rules of monopoly are completely unwritten

aproduct of human greed and desire

Lyxal

4:51 AM

@RedwolfPrograms technicalities?

It's pretty simple

Buy or auction

No free parking bonus

No extra go money

No taxes to the centre

And no loans

Simple

@Razetime I've actually finished more games than that

Again about the table lookup computation challenge, what should be included in the header? From the sandbox feedback I guess that that's probably the only remaining problem.

Although that's just a minor details.

Should I make another meta post to make absolutely sure that people are okay with the combined score thing?

Q: Efficient table-lookup computation

The challenge: compute the day of the week from a MM-DD representation of a day in this year (2021). However, you have to write your program in the following subset of Python: (I chose Python because it's popular and easy to understand even to the people who doesn't know the language. Obviously y...

Q: Count strictly overlapping substrings

Given two strings a and b, count how many times b occurs as a substring in a, but only when it overlaps with another instance of b. (This means that 1 will never be a valid output, because in order for the substring to be strictly overlapping, there must be at least one other instance for it to o...

(about my recent challenge) I believe the minimum value of A is 20. I didn't have a program for that however.

Okay @SheikYerbouti

First are you familiar with the language Python?

Sheik Yerbouti

No, but I get that T is a table of key/value pairs. A bit like array elements with their index

I know only C and some JavaScript

user202729

Huh, about the basic parts (variables assignment, dict) they're pretty similar.

Perhaps the part you don't get is just

Wow, Arnauld is one repcap away from being the 4th Legendary person on the site :P

Sheik Yerbouti

Yes I don't know what you meant with that phrase, but my main concern is knowing what are keys and values representing

user202729

They don't really represent anything.

They're... just part of the program, and the program needs the dict to work.

Sheik Yerbouti

1:59 PM

Huh, so looking at "ovs" I may have get that the point is to compute the day of the week using only addition. Is this the point of the challenge?

user202729

Using only string lookup and concatenation.

The particular operations allowed is defined in the challenge.

Apart from that, yes.

Sheik Yerbouti

All right, and if it's not asking too much, how the concatenation works? I put a "+" sign between two keys and the result is the concatenation of their values? Like if I have "01":"1", "02":"2"; I would use concatenation on the keys "01"+"02" to obtain "12". I am just guessing.

user202729

@SheikYerbouti Exactly like in JavaScript. You use + to concatenate two strings to get a new string.

It's not a special language. It's just Python.

(anyone feel like creating a chat room for that challenge?)

the default.

@user202729 is that a lower bound, or do you think it's actually possible to create such an answer?

user202729

@thedefault. It might be possible. I'm trying. I think I'm close.

All right I will try to wrap my head around the text of the challenge, googling some Python. Thank you for the explanations

user202729

That same code will probably work in JavaScript anyway.

user202729

2:34 PM

Okay, I can confirm that there exists a universal ("functionally complete") 10-ary function, and that there exists an A=20 solution.

Not that I actually constructed one.
