Today We Did

1. We continued with exploring more List practices
   1. printForwardEveryOtherElement
   2. swapFirstAndLast
   3. flipList

Homework

Inside Sep23ArrayAndListIteration.java

1. finish the boolean isPalindrome(String[] text) method. This is similar to how flipList method works.
2. study how to Java String substring functions works. Look at example in https://www.w3schools.blog/substring-in-java . So basically you need to know how to iterate one letter at a time in a String.
3. Once you figure out how Java String substring works, create a new  method boolean isPalindrome(String text) method. This one is very similar to #1 but the parameter is String text instead of String[] text.
