24-point calculator (console program including C # source)

Description:

There is no other way. You only need to calculate all kinds of possibilities, and then get an expression that can calculate 24, and eliminate repeated expressions as much as possible.

Assume that there are four numbers of a B c d, and the operator is replaced by OP, there are (a op B) OP (c op D) or (a op B) op C) OP d

ProgramDeveloped in C #2.0 and supports computing 8/(3-8/3) = 24

The biggest headache of this program is how to get rid of repeated results. I have rewritten the gethashcode () method to make repeated expressions calculate the same value as much as possible.

Syntax:

Calc24 [num1 [num2 [num3 [num4]

Example:

Calc24 3 3 8 8
Calc24 3 3 8
Calc24 3 3
Calc24 3
Calc24

If the parameter is omitted, the program automatically generates a random number of less than 24
