Task
Define a mod-fold as a function of the form f(x) = x % a1 % a2 % … % ak, where the ai are positive integers and k ≥ 0. (Here, % is the left-associative modulo operator.)
Given a list of n integers y0, …, yn−1, determine if there exists a mod-fold f so that each yi = f(i).

What is chat supposed to be anymore? Lately whenever I come by on one of my infrequent visits, I'm unsure if what I post is appropriate for the chatroom. I used to treat it like when I just talk to my friends or random people, but now I'm not sure how site-oriented it is supposed to be...
So I've been having this thought. My family has almost managed to visit all 50 states in the United States and I thought it would be interesting to know the years in which we visited each one. Unfortunately, this would be quite difficult because digging through all the information would take some time. It would be easy, however, if we just had a database of it all. So I've been thinking: what if I just record my life in a database?
It's like a journal, except completely unstructured...
@MatthewRoh Most instructions have a direct equivalent. jmp is [, jnz is ], get is ,, put is ., rwd is <, fwd is >, sub is -, and add is +. The main difference is that you write add 5 instead of +++++.
@Justin I've actually started doing that on a small scale. I record the tasks I get done each day in a Google doc. Not just errands, but also stuff like social events, reading books, watching videos/movies/TV shows, etc.
Has anyone ever used VEX robotics? I brushed the dust off an old VEX starter kit today, and I'm trying to see how difficult it is to add custom programming. It looks like it requires a special piece of hardware.
It also looks like I'm in luck, since they released the legacy software for free: robotc.net/download/vex
Question: what would be more useful in a stack-based language whose stack is empty? 1. Use last pushed item for pop()'s with empty stack 2. Use last popped item for pop()'s with empty stack 3. Read a line of input for pop()'s with empty stack 4. Use the last thing inputted for pop()'s with empty stack
I will have a command-line flag to change which option to use, but which should be default?
more seriously, I'd rather avoid doing it because A) it's less confusing when you can simply say 'import' statement because it begins with import B) I'm not going to do something just because python does it
Anyone here have an algorithm for finding all permuations of n elements of a list l lying around? My goal is to turn l=[1 2 3], n=2 into [1 2] [2 1] [1 3] [3 1] [2 3] [3 2] (not necessarily in that order)
I'm making a bunch of builtin list/stream constructors for popular sequences for a golfing language I'm writing, what sequences should I definitely add in?
I am most certainly not! How dare you make such an allegation! (I actually tried to change this to my real name recently, but it seems like that didn't work. :P)
Which ghosts are missing?
In this challenge, given a list of ghosts from Pac-Man, you must output which ghosts are missing.
Input
Input will consist of a string, which will be a list of ghosts, which are;
Blinky
Inky
Pinky
Clyde
However, the list may also include Pac-Man (with that punctua...
I want to change one of my keys on my keyboard to a Compose key so I can easily type common accents or characters, e.g.: Compose+e+' -> é.
Is there a setting I can change or a program I can install to add this feature? For instance, I would like to use Caps Lock as Compose.
Write a program which outputs the square root of a given number in the shortest time possible.
Rules
It may not use any builtins or powering with numbers between 0 and 1.
Given number means submitted
as a function argument
as a command line argument
as a direct input on stdin or a window
