fizzbuzz's Issues

Create classic FizzBuzz solution

The problem description is the following (adapted from https://wiki.c2.com/?FizzBuzzTest):

"Write a program that generates the numbers from 1 to n. But for
multiples of three gives “Fizz” instead of the number and for the
multiples of five gives “Buzz”. For numbers which are multiples of both
three and five gives “FizzBuzz”."

For example:

>>> list(classic_fizzbuzz(20))
['1', '2', 'Fizz', '4', 'Buzz', 'Fizz', '7', '8', 'Fizz', 'Buzz', '11', 'Fizz', '13', '14', 'FizzBuzz', '16', '17', 'Fizz', '19', 'Buzz']

Review and complete docs

Make a general parametrized version of FizzBuzz.

This version must allow to specify a set of conditions with its respective replacements functions and a common transformation to be applied to each resultant replacement in a way that each final replacement will expose a common trait.

For example:

>>> mod3 = lambda e: e % 3 == 0
>>> mod5 = lambda e: e % 5 == 0
>>> mapping={mod3: lambda e: 'Fizz', mod5: lambda e: 'Buzz'}
>>> fusion = lambda ac, r: ac+r
>>> assert list(classic_fizzbuzz(100)) == \
            list(general_fizzbuzz(iterable=range(1, 101), mapping=mapping,
...                              default=str, fusion=fusion, common=lambda r: r))

>>> assert classic_fizzbuzz_as_text(100, ', ') == \
            ''.join( general_fizzbuzz( iterable=range(1, 101),
...                                   mapping=mapping,
...                                   default=str, fusion=fusion,
...                                   common=lambda r: f'{r}, '   ) )

>>> list(  general_fizzbuzz(  iterable=range(55, 61),
...                           mapping={ mod3: lambda e: 'Fuzzy',
...                                     mod5: lambda e: 'Buzzy'  },
...                           default=lambda x: 'Normal',
...                           fusion=fusion,
...                           common=lambda r: f'({r})'              )  )
['(Buzzy)', '(Normal)', '(Fuzzy)', '(Normal)', '(Normal)', '(FuzzyBuzzy)']

>>> list(  general_fizzbuzz(  iterable=range(55, 61),
...                           mapping={ mod3: lambda e: (e, 'Fuzzy'),
...                                     mod5: lambda e: (e, 'Buzzy')  },
...                           default=lambda x: 'Normal',
...                           fusion=lambda ac, r: (ac[0], ac[1]+r[1]),
...                           common=lambda r: r                          )  )
[(55, 'Buzzy'), 'Normal', (57, 'Fuzzy'), 'Normal', 'Normal', (60, 'FuzzyBuzzy')]

Add CLI option to use web services

Add options to use the web services from the CLI.

Add codecov integration

Organize folder structure

Add web services

Create two services. The first gives the classic FizzBuzz result in the body of a sole response. The other gives the result as a stream. The services must have two parameters: n is the maximum number in the sequence, sep is the separator used to separate each member of the resulting sequence. Keep the trailing sep at the end of the resulting sequence. For example:

$> curl -X GET "http://${SERVER}/classic-fizzbuzz/?n=10&sep=, "
1,2,Fizz,4,Buzz,Fizz,7,8,Fizz,Buzz,

where $SERVER is the server dir.
