Notes to Tabs
code-golf kolmogorov-complexity
Challenge
Given a list a notes, you must return the corresponding tablature.
Notes
The notes must be in the range of A to G inclusive and the octave range being 2 to 7 inclusive. The format is note-octave with # representing a sharp and b represe...
Wireworld is a cellular automaton that was designed to be resemble electrons flowing through wires. Its simple mechanics allow the construction of digital circuits. It has even permitted the construction of an entire computer.
Your mission is to create the shortest Wireworld implementation in y...
PFD, HCF & LCM
code-golf math
Challenge
Given two numbers, you must find the prime factor decomposition (PFD) of the two numbers, then using the PFD of each number, calculate the highest common factor (HCF) and the lowest common multiple (LCM).
Examples
Input: 20, 40
Output:
20= 2^2 * 5
40 ...
Program to solve a Tetris puzzle
The challenge is about finding an optimal solution on how to place a number of given shapes. It is oriented on the principle of Tetris, where it is optimal to pack the given pieces as tight as possible.
These are the rules:
There are predefined Tetris shapes...
@MartinBüttner "Each event is either a list of dying characters, or a list of groups of characters (signifying which characters are currently together)". I presume that [[0],[1,2,3],[4],[5,6],[7,8,10,11,12],[9],[13]] means that characters 0, 4, 9, and 13 are each alone but alive. That could be clearer. Even more importantly, you could clarify whether the "together" lists in which a character appears will be contiguous; and whether it's guaranteed that all characters appear in the first one.
Yes, it's fundamentally a question about the minimum amount of state which needs to be tracked.
The other thing is that you might want to mention that output can be vector or raster graphics file or display on screen (or whatever subset of that you want to accept).
I'll never get people's voting patterns. You post an answer, spend waaay too much time thinking about how to improve it, and minutes after you do, you get a downvote...
@Peter Taylor, Duplicate Police Officer, do you have any suggestions? ^ ;)
Validation isn't too interesting, because there's a fairly simple regex for it. But I think that leaves only comparison and sorting, which are essentially the same. Of course, there's also the possibility for a program that bumps version numbers, but that's also not as interesting as comparison. It's just that that seems very close to the debian versioning one.
