Modify the Strings array program.
Use correct documentation and add the appropriate test code in the main method to test your methods.
Create three methods, left, right and mid.
Create a method called left that accepts an array of characters and the number of characters to return.
This method should return a new array of characters with the number of of the characters passed.
if you enter left(“Hello”, 2); // it returns He because those are the first 2 characters on the string
if you say right(“Hello”, 2); // It should return “lo” because those are the last 2 characters of the string
if you say mid(“Hello”, 2, 2); // It should return “ll”, the first number is the beginning index and the second number the number of characters.
