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 RegEx exercise 2, should I accept strings that have more than three consecutive vowels?

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).

Unacceptable Batting Average Outputs
