Pig Latin Encoder

To encode a word in pig latin, we need to handle two cases as described on p. 277.

The following function is a partial (but not complete) solution.

For example, how does it encode swing? rhythm? Aardvaark? CIS?

/* return word w encoded as pig latin */

function encode(w){
  if(w.search(/[aeiou]/) == -1 || w.search(/[aeiou]/) == 0)
     return w + 'way'
  else
     return  w.substring(1, w.length) +  w.charAt(0) + 'ay'
}

MISC PIG LATIN NOTES

var w = 'oops!!'
var punct, bareWord, pLatin, ans

//peel off punctuation
punct = w.substring(w.search(/[!,.]/), w.length)
bareWord = w.substring(0, w.search(/[!,.]/))

pLatin = encode(bareword)

ans = pLatin + punct

Test Cases:

Eighthstreet, gym, myrrh, aeon, llama, kvetch.

gnome, bloom, brew, clue, snow, smart, wrench.

rhythm, crypt, rhyme, gypsy, strength, scrimp, shrimp, schlep, shrapnel, splice, sphygmomanometer, strap, scrap, spring,

Pig Latin koans: Xylophone, tsktsk, eau de Cologne.

Final Exam Review Problems

• (1) Write an alarmClock() function that accepts an integer representing the day of the week (Mon=1, Tue=2, ... Sun=7) and returns a string: On weekdays the clock tells us to get up, and weekends it tells us to snooze more. On Monday, the clock adds some extra harassment to get us out of bed.
  
  Examples
  
  alarmClock(2) => Hi ho, hi ho, it's off to school we go...
  
  alarmClock(6) => Hit the snooze button!
  
  alarmClock(1) => Daylight in the swamps! Up and at'em!
  
  Strategy: Use an else-if (See fig. 11.7, p. 203; dice.html)
• 
  
• _______________________________________________
  
  (2) Write a bowlingScoreFeedback() function that accepts a bowling score 0 .. 300 and returns one of these messages:
  
  300: "most triumphant!"
  200..299: "pretty good!"
  50..199: "making progress!"
  0..49: "better take up Scrabble!"
  
  Examples
  
  bowlingScoreFeedback(250) => pretty good!
  
  
  bowlingScoreFeedback(25) => better take up Scrabble!
  
  _________________________________
  
  (3) Suppose you want to get a table at a hip restaurant: The variable "style" represents the stylishness of your clothes and "bribe" represents the bribe presented to the Maitre'd.
  
  The Maitre'd is satisfied if style is 8 or more and bribe is 5 or more.
  
  One way to code this up is to write the "satisfied" expression as a straight translation of the problem statement, and then put a ! in front of it:
  

  //Say something mean if not satisfied
  function maitreD(style, bribe){
  if (! ((style >= 8) && (bribe >= 5)) ) {
     return "tant pis pour vous"
  else
     return "Ainsi, s'il vous plaît"
  }

Google's Book Search: A Disaster for Scholars

Google's book search is clearly on track to becoming the world's largest digital library. Will it support scholarly research as well as bricks-and-mortar libraries? Metadata will be the deciding factor.
