	~~Brainfk~~, designed by Urban Müller in 1993 to contain the smallest possible compiler, supplies programmers with only eight commands. Normal ~~Brainfk~~ compilers have access to a limitless number of memory cells, each containing a single [[Wikipedia:Unsigned integer\|unsigned integer]] ranging from 0 to 255. Commands are used to shift the 'selected cell' left or right one step at a time, input numbers into cells, increment or decrement the selected cell, and run commands if the selected cell contains a non-zero value.

Brainfuck programs run from left to right, running each command until the end is reached (excluding cases of the [[Wikipedia:Halting problem\|Halting problem]]). The only exception is with Loops, which work in a specific way.

	Each Open must be paired with a Close. Once a program reaches an Open, it checks whether the selected cell's value is zero. If it is, the loop is ended, and the program skips ahead to the Open's corresponding Close. Otherwise, the loop is unlocked; the program advances to the first command inside the loop, moves right, and repeats the process as needed.		Each Open must be paired with a Close.
