Daily Interview Problem: Word Ordering in a Different Alphabetical Order

Hi, here's your problem today. This problem was recently asked by Apple:

Given a list of words, and an arbitrary alphabetical order, verify that the words are in order of the alphabetical order.

Example:
Input:

words = ["abcd", "efgh"], order="zyxwvutsrqponmlkjihgfedcba"

Output: False
Explanation: 'e' comes before 'a' so 'efgh' should come before 'abcd'

Example 2:
Input:

words = ["zyx", "zyxw", "zyxwy"],

order="zyxwvutsrqponmlkjihgfedcba"

Output: True
Explanation: The words are in increasing alphabetical order

Here's a starting point:

def isSorted(words, order):

  # Fill this in.



print isSorted(["abcd", "efgh"], "zyxwvutsrqponmlkjihgfedcba")

# False

print isSorted(["zyx", "zyxw", "zyxwy"],

               "zyxwvutsrqponmlkjihgfedcba")

# True
