Binary Converter
In this exercise you will be making functions that convert between base 10 numbers and binary.
Binary notation is based on powers of 2. Each digit is a power of 2. The first digit is 2^0, second 2^1, etc... You then add all of the digits together.
For example, 101 is 5 (4 + 1). 110 is 6 (4 + 2). 1100 is 12 (8 + 4)
Here is a chart of some base 2 vs base 10 notation numbers:
0.....0
1.....1
10.....2
11.....3
100.....4
101.....5
110.....6
111.....7
1000.....8
1001.....9
1010.....10
1011.....11
1100.....12
1101.....13
####Step 1
Write a method that takes binary numbers and outputs a base 10 number.
binary_to_decimal(1011) ## returns 11
####Step 2
Write a method that takes decimal numbers and returns it in binary notation.
decimal_to_binary(12) ## 1100
