# 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](https://en.wikipedia.org/wiki/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. The submit command will look something like: ```shell exercism submit <path-to-exercism-workspace>/objective-c/all-your-base/AllYourBase.m ``` You can find the Exercism workspace by running `exercism debug` and looking for the line beginning with Workspace. ## Submitting Incomplete Solutions It's possible to submit an incomplete solution so you can see how others have completed the exercise.
