# All Your Base

Convert a number, represented as a sequence of digits in one base, to any other base.

Implement general base conversion. Given a number in base **a**,
represented as a sequence of digits, convert it to base **b**.

## Note

- Try to implement the conversion yourself. Do not use something else to perform the conversion for you.

## About Positional Notation

In positional notation, a number in base **b** can be understood as a linear
combination of powers of **b**.

The number 42, *in base 10*, means:

(4 * 10^{1)} + (2 * 10^{0)}

The number 101010, *in base 2*, means:

(1 * 2^{5)} + (0 * 2^{4)} + (1 * 2^{3)} + (0 * 2^{2)} + (1 * 2^{1)} + (0 * 2^{0)}

The number 1120, *in base 3*, means:

(1 * 3^{3)} + (1 * 3^{2)} + (2 * 3^{1)} + (0 * 3^{0)}

I think you got the idea!

*Yes. Those three numbers above are exactly the same. Congratulations!*

## Setup

There are two different methods of getting set up to run the tests with Objective-C:

- Create an Xcode project with a test target which will run the tests.
- Use the ruby gem
`objc`

as a test runner utility.

Both are described in more detail here: http://exercism.io/languages/objective-c

### Submitting Exercises

When submitting an exercise, make sure your solution file is in the same directory as the test code.

For example, if you're submitting `Bob.m`

for the Bob exercise, the submit command would be something like `exercism submit <path_to_exercism_dir>/objective-c/bob/Bob.m`

.

## Submitting Incomplete Solutions

It's possible to submit an incomplete solution so you can see how others have completed the exercise.
