Helper method for conversion
Takes binary number and converts to a list of
grouped binary values
Process:
1. convert number to a list of chars
2. reverse the list
3. iterate through the list creating groups of 4
removing each value as its iterated
4. if the remaining values can not make a group,
add 0's to the end to get to 4
5. join each list together
6. reverse each value in the final list to put
them back in order
Example:
n = 11101100101001001100101001
reverse = 10010100110010010100110111
Start grouping values:
[['1', '0', '0', '1'],
['0', '1', '0', '0'],
['1', '1', '0', '0'],
['1', '0', '0', '1'],
['0', '1', '0', '0'],
['1', '1', '0', '1']]
remaining value = 11
add missing 0's -> 1100
join each list:
['1', '0', '0', '1'] = 1001
['0', '1', '0', '0'] = 0100
['1', '1', '0', '0'] = 1100
['1', '0', '0', '1'] = 1001
['0', '1', '0', '0'] = 0100
['1', '1', '0', '1'] = 1101
['1100', '1101', '0100', '1001', '1100', '0100', '1001']
reverse final list
