Problem Statement |
| | Your company has just undergone some software upgrades, and you will now be storing all of the names of your clients in a new database. Unfortunately, your existing data is inconsistent, and cannot be imported as it is. You have been tasked with writing a program to cleanse the data.
You are given a String[], names, which is a list of the names of all of your existing clients. Some of the names are in "First Last" format, while the rest are in "Last, First" format. You are to return a String[] with all of the names in "First Last" format, sorted by last name, then by first name.
