Whether it is real or on the Wii, bowling is a fun game. (Okay, for
the sake of the quiz, let’s assume it’s a fun game.) But I’ve known
folks who just don’t understand how to score properly. They can
count pins knocked down, and know that getting all ten pins in one
roll is good, but they still can’t keep score.
Your task this week is to tally scores for these people. The input
will be the player’s name and the number of pins felled from each
roll. For example:
ruby bowling_scores.rb John 6 2 7 1 10 9 0 8 2 10 10 3 5 7 2 5 5 8
Your should tally the per-frame scores and generate output in table
form, such as:
John's final score: 140 Frame Roll Roll Score 1 6 2 8 2 7 1 16 3 X 35 4 9 - 44 5 8 / 64 6 X 87 7 X 105 8 3 5 113 9 7 2 122 10 5 / 140 * 8
Note that you should make use of typical bowling symbols:
X for a
/ for a spare, and
- for zero. Also, if extra balls were
thrown at the end (to supplement a strike or spare in the final
frame), list those as frame
* like the above, but without a score.
Extra credit: Generate ascii or graphical output that looks more like
the traditional bowling score form, which can be seen on this page.
