Solves the game 24 using brute force

Given a 4-digit number, manipulate the digits using the allowed operations to come to 24.

Allowed operations: addition, subtraction, multiplication, division, exponentiation

Number: 1234

Possible solution: (1 * 2) * (3 * 4) = 24

Another solution: ((1 + 2) + 3) * 4 = 24

Another solution: (2 ^ 3) * (4 - 1) = 24

Another solution: (4 * 3) * (2 / 1) = 24

etc.

This program is a Python3 solver for 24 that brute forces all possible results. It has three modes depending on which lines you uncomment.
