Given a text like this:
# #### ## #
## # ## #
#### ##
Output the same text but by connecting the pixels with the characters ─│┌┐└┘├┤┬┴┼. If a pixel doesn't have any neighbours, don't change it.
So the output of the last text is:
│ ─┬── ┌─ │
└─ │ ┌┘ │
└──┘ ─┘
You can take input...
Goal
Your goal is to multiply two numbers using only a very limited set of arithmetic operations and variable assignment.
Addition x,y -> x+y
Reciprocal x -> 1/x (not division x,y -> x/y)
Negation x -> -x (not subtraction x,y -> x-y, though you can do it as two operations x + (-y))
The const...
You are given as input two strings representing positive integers in base 10, such as "12345" and "42". Your task is to output a string containing their product, "518490" in this case.
The twist is that you may not use any numerical types in your code. No ints, floats, unsigned longs, etc., no b...
A Rubik's cube has 6 colors: red, orange, yellow, white, blue, and green. Red and orange, yellow and white, and blue and green faces are on opposite sides.
Net of a solved Rubik's cube looks like this:

Bob's job is to create spreadsheets and organize them. The way he organizes them is known to very few except for Bob, but he creates a list of each of the spreadsheets that fall under the same group. There's a bunch of data in the spreadsheet ...
Convert an integer to the prime-base number system.
code-golfnumberprime
The prime-base number system is a number system which I just made up. While normal number systems are based on taking the sum of each numbers value, the prime-base number system is based on taking the product instead.

King me?
Challenge:
Given a checkerboard, output the smallest amount of moves it would take (assuming black does not move at all) to king a red piece, if possible.
Input:
An 8x8 checkerboard, with spaces defined as the following characters(free to use alternatives):
. - Empty
R - Red piece(...
I am having some difficulty compiling a C++ program that I've written.
This program is very simple and, to the best of my knowledge, conforms to all the rules set forth in the C++ Standard. I've read over the entirety of ISO/IEC 14882:2003 twice to be sure.
The program is as follows:
Here i...

Well, the traditional generic name for the country club bar is "the nineteenth hole", which suggests The Nineteenth Byte or something like that.
Is it an Odd Word?
code-golf alphabet
Challenge
Given a single word as input, determine if the word is odd or even.
Odd and Even words
Assume the general rules:
odd + odd = even
even + odd = odd
odd + even = odd
even + even = even
In the alphabet, the odd letters are:

One nice property of a Turing-complete language is that it can be used to write any program, up to and including the simulation of the entire Universe.
Your job is to do exactly that: write a program which simulates the Universe.
Note: although I don't doubt you'll be able to accomplish this ...
