## Five remaining lectures

• Experiment: Let's write some programs together
• Learning goals:
• Apply what we've been learning in class
• Collaborate
• I have no idea how this will work out

## Problem definition

• Vince Young got my wife and I addicted to the iPhone app called Ruzzle
• It's a 4 by 4 board filled with tiles
• Each tile has a point value associated with it that is proportional to the probability of seeing it in a word (think Scrabble)
• Sometimes there are double letter and double word tiles
• You have two minutes to get as many words as possible
• I'm not very good.

## Point values

``````point.values = c(
'A' = 1,  'B' = 3,  'C' = 3,  'D' = 2,
'E' = 1,  'F' = 4,  'G' = 2,  'H' = 4,
'I' = 1,  'J' = 8,  'K' = 5,  'L' = 1,
'M' = 3,  'N' = 1,  'O' = 1,  'P' = 3,
'Q' = 10, 'R' = 1,  'S' = 1,  'T' = 1,
'U' = 1,  'V' = 4,  'W' = 4,  'X' = 8,
'Y' = 4,  'Z' = 10
)
``````
