1) *in python*

a. Given a string, determine if the string begins with "green" or "purple" and if it does, return that color string. Otherwise, return an empty string.

Examples:

seeColor("greenxx") -> "green" seeColor("xxgreen") -> ""

b.

Given a string, count the number of words ending in 'y' or 'z'--so the 'y' in "heavy" and the 'z' in "fez" count, but not the 'y' in "yellow" (not case sensitive). We'll say that a y or z is at the end of a word if there is not an alphabetic letter immediately following it. (Note: isalpha() returns True if all characters in a string are alphabetic letters.)

Examples:

countYZ("fez day") -> 2 countYZ("day fyyyz") -> 2
