Take an integer n as function input, or STDIN. n can be between 20-400. Create a random list of numbers, where the first number, num1 is a random integer between 1 and n. The second number is a random integer between 1 and n-2*num1, the third number is a random integer between 1 and n-num1-2*num2...
Ulam's spiral is a truly fascinating, yet puzzling, topic in mathematics. How it works in detail can be found here, but a short summary can be explained as so:
I start off by writing a one, then I write a two to the right of it. Above the two, I write a three, and to the left of that I write fou...
I need to make a program that reads characters for playing the game rock paper scissors.
If the character entered by the user is not rock paper or scissors, the program prompts the user until they enter rock paper or scissor.
I also need to use a while loop
Background
Last time, we counted groups of a given size, which is a non-trivial problem.
This time, we'll only count Abelian groups, i.e., groups with a commutative operation. Formally, a group (G, ∗) is Abelian if x ∗ y = y ∗ x for for all x, y in G.
The problem becomes much simpler this way,...
Mathematica 10.1, indium (49)
This solution uses a built-in library of element properties, including IUPAC names and abbreviations. (I haven't seen this as a technique to be avoided in Golf. It seems to be encouraged. But this might be on (perhaps over) the edge of acceptable -- Mathematica i...

This happens to meet both the second and third requirements.
Cops and Robbers: String Printing
cops-and-robbers
Cops task
Write a program that prints a string to STDOUT.
The robbers will try to write a program that prints the same string.
The string must consist of only printable ASCII characters (no control characters besides CR,LF,FF,TAB, and an opti...
I think that we should tag puzzles (or whatever) with an estimated difficulty tag. That way people who want a real challenge can find it and those who are just starting out can find ones they might be more able to solve.
For example consider: Distance between hands on clock
vs: Shortest path i...
