# This Python 3 script solves the "Four Fours" problem and similar problems.

# The example at the end of the script generates all combinations of [2,3,5,7]
# that equal 10, using the operations of addition, subtraction, multiplication,
# and division.

# Exact arithmetic is used. Only integer exponents between -99 and 99 are allowed.

# This programs solves additive cryptarithms using brute force.

# Example: solve_cryptarithm(['SEND', 'MORE', 'MONEY']) returns a list of
# all solutions to the equation SEND + MORE = MONEY, where each letter 
# stands for a different digit in base 10. Leading zeros are not allowed.

# This little Python script was written to explain XKCD comic #1787 (Voice Commands).
# In the comic, Cue Ball has reprogrammed his phone to use the Dvorak keyboard layout
# for voice recognition. (See http://xkcd.com/1787/)

# For those who don't know, the standard keyboard layout in the United States is called
# QWERTY, after the first six letters in the first row of letters. But there are a few
# enthusiasts who advocate an alternative layout, called Dvorak. These layouts have the
# same characters, but in different positions, as shown below.
