// The idea of this assignment is to take an existing array of names
8+
// and then output either Hello 'Name' or Good Bye 'Name' to the console.
9+
// The program should say "Hello" to any name except names that start with a "J"
10+
// or "j", otherwise, the program should say "Good Bye". So, the final output
11+
// on the console should look like this:
12+
/*
13+
Hello Yaakov
14+
Good Bye John
15+
Good Bye Jen
16+
Good Bye Jason
17+
Hello Paul
18+
Hello Frank
19+
Hello Larry
20+
Hello Paula
21+
Hello Laura
22+
Good Bye Jim
