== Regular Expressions Cases ==

=== When parsing for a string, should I look for that string exclusively or that string concatenated with other characters? ===
If you are looking for a string, you should be looking for any exact occurrences of that string. This is the case regardless of what characters are appended to the beginning or the end of said string.

'''Example:''' Parsing for "hello world"

'''What Should Work'''

hello world, hi hello world, hello worldwide, hhhello worlddd

'''What Shouldn't Work'''

hello weorld, hello to the world

In this exercise, strings with three ''or more'' vowels should be accepted.

'''What Should Work'''

beautiful, queue, coooool!

=== In RegEx exercise 3, is each line a separate input? ===
Yes. Each line with a potential flight code is a separate input. Your expression does not need to account for separating each potential code.

=== If a batting average ends in a 0, can I round to two decimal places? ===
A batting average must always be rounded to 3 decimal places, regardless of if it ends in one (or more) zero(s).

'''Expected Batting Average Outputs'''

.270, .300, .050

'''Unacceptable Batting Average Outputs'''

.27, .3, .05
