# 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!*
