    Week 1 Homework


Complete the ruby koans
Use RSpec to test-drive a solution to either:

Bowling Kata, or
Harry Potter Kata


Write a 10 minute presentation about the topic card you pick
BONUS: clone Corey Haines' [practice repo] 1, and use it to help you complete a Game of Life solution.

You will need to research [cucumber] 2 and [bundler] 3
Use cucumber and rspec to help guide your code
Look out for when things feel more appropriate to test with rspec or with cucumber

    Create a program, which, given a valid sequence of rolls for one line of American Ten-Pin Bowling, produces the total score for the game. Here are some things that the program will not do:

We will not check for valid rolls.
We will not check for correct number of rolls and frames.
We will not provide scores for intermediate frames.
Depending on the application, this might or might not be a valid way to define a complete story, but we do it here for purposes of keeping the kata light. I think you'll see that improvements like those above would go in readily if they were needed for real.

We can briefly summarize the scoring for this form of bowling:

Each game, or "line" of bowling, includes ten turns, or "frames" for the bowler.
In each frame, the bowler gets up to two tries to knock down all the pins.
If in two tries, he fails to knock them all down, his score for that frame is the total number of pins knocked down in his two tries.
If in two tries he knocks them all down, this is called a "spare" and his score for the frame is ten plus the number of pins knocked down on his next throw (in his next turn).
If on his first try in the frame he knocks down all the pins, this is called a "strike". His turn is over, and his score for the frame is ten plus the simple total of the pins knocked down in his next two rolls.
If he gets a spare or strike in the last (tenth) frame, the bowler gets to throw one or two more bonus balls, respectively. These bonus throws are taken as part of the same turn. If the bonus throws knock down all the pins, the process does not repeat: the bonus throws are only used to calculate the score of the final frame.
The game score is the total of all frame scores.

    Harry Potter Kata

To try and encourage more sales of the 5 different Harry
Potter books they sell, a bookshop has decided to offer
discounts of multiple-book purchases.
One copy of any of the five books costs 8 EUR.
If, however, you buy two different books, you get a 5%
discount on those two books.
If you buy 3 different books, you get a 10% discount.
If you buy 4 different books, you get a 20% discount.
If you go the whole hog, and buy all 5, you get a huge 25%
discount.
Note that if you buy, say, four books, of which 3 are
different titles, you get a 10% discount on the 3 that
form part of a set, but the fourth book still costs 8 EUR.
Your mission is to write a piece of code to calculate the
price of any conceivable shopping basket (containing only
Harry Potter books), giving as big a discount as possible.
For example, how much does this basket of books cost?
2 copies of the first book
2 copies of the second book
2 copies of the third book
1 copy of the fourth book
1 copy of the fifth book
Answer: 51.20 EUR
