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 * 101) + (2 * 100)

The number 101010, in base 2, means:

(1 * 25) + (0 * 24) + (1 * 23) + (0 * 22) + (1 * 21) + (0 * 20)

The number 1120, in base 3, means:

(1 * 33) + (1 * 32) + (2 * 31) + (0 * 30)

I think you got the idea!

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

 `1` ```% exercism debug | grep Workspace ```
2. Get PHPUnit if you don't have it already.

 ```1 2``` ```% wget --no-check-certificate https://phar.phpunit.de/phpunit.phar % chmod +x phpunit.phar ```
3. Execute the tests:

 `1` ```% ./phpunit.phar all-your-base/all-your-base_test.php ```
