Week 1, Extra Problem
1: Pig Latin
[15
points; individual or pair]

[5 points]
Write pigLatin( s ),
which will take as input a string s. s will be a single word consisting of
lowercase letters. Then,
pigLatin should
output the translation of
s to
pig latin, according to these slightly altered rules:
If the input word has no letters at all (the empty
string), your function should return the empty string
If the input word begins with a vowel, the pig latin
output simply appends the string 'way' at the end. 'y' will be considered a consonant, and
not a vowel, for this problem.
Hint: Consonant
letters in the English alphabet are B, C, D, F, G, H, J, K, L, M, N, P, Q, R,
S, T, V, W, X, Z, and Y.
Example
pigLatin('one') returns 'oneway'
If the input word begins with a consonant, the pig
latin output is identical to the input, except that the input's initial consonant
is at the end of the word instead of the beginning and it's followed by the
string 'ay'.
Example
pigLatin('be') returns 'ebay'
Of course, this does not handle words beginning with
multiple consonants correctly. For example, pigLatin('string') returns 'tringsay'.++
Don't
worry about this. However, if you would like to tackle this more challenging
problem, see the extra credit, below... .
The real
pig latin challenge
[10 points]
Create a function called spamLatin(
s ) that
handles more than one initial consonant correctly in the translation to Pig
Latin. That is, spamLatin moves all of the
initial consonants to the end of the word before adding 'ay'. (You may want to write and
use a helper function to do this.)
Also, spamLatin should handle an initial 'y' either as a consonant OR
as a vowel, depending on whether the y is followed by a vowel or consonant,
respectively. For example, 'yes' has an initial y acting as a consonant. The
word 'yttrium', however
-- element #39 for anyone who's as chemically challenged as I am -- has an
initial y acting as a vowel. Here
are some additional examples:
>>> spamLatin('string')
ingstray
>>> spamLatin('yttrium')
yttriumway
>>> spamLatin('yoohoo')
oohooyay
If you think about this problem thoroughly, you'll find
that not every possible case has been accounted for - you are free to decide
the appropriate course of action for those "corner cases."
