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

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!

The Scala exercises assume an SBT project scheme. The exercise solution source should be placed within the exercise directory/src/main/scala. The exercise unit tests can be found within the exercise directory/src/test/scala.

To run the tests simply run the command sbt test in the exercise directory.

For more detailed info about the Scala track see the help page.
