SymbolSum Solver

================

I haven't figured out how to do these by hand yet, but who cares, let Python do

the job!

Problem

-------

You are given an arithmetic problem where the numbers have been replaced with

symbols. Your job is to determine the number values of the symbols.

The numbers are single digits, i.e. [0-9] and all unique.

![Problem](https://raw.github.com/jsok/symbolsum-solver/master/problem.jpg)

Usage

-----

For the above problem, enter it as:

```

    # List of symbols that appear in the problem

    all_symbols = ['star', 'circle', 'hexagon', 'plus', 'triangle']

    # Direct translation of symbols

    # If you know a number, e.g. 0, leave it in and it will help speed things up

    operand1 = [ 'triangle', 'plus', 'plus', 'hexagon', 'hexagon' ]

    operand2 = [  0,  'plus', 'star', 'circle', 'star' ]

    result  = [ 'star', 'circle', 'hexagon', 'circle', 'star' ]

    # Instatiate a SymbolSumSolver

    solver = SymbolSumSolver(all_symbols)

    # You can use the operator's in the standard python operator module

    import operator

    solver.solve(operand1, operator.sub, operand2, result)

```

Output:

```

    Found 1 solutions:

    - 03494

      49894

    Therefore: {'plus': 3, 'circle': 9, 'hexagon': 8, 'triangle': 5, 'star': 4}
