Write a function called rotateRight that takes a string as its first argument and a non- negative int as its second argument and rotates the String by the given number of characters. Here's what we mean by rotate: CS125 rotated right by 1 becomes 5C512 C5125 rotated right by 2 becomes 25C51 C5125 rotated right by 3 becomes 125CS C5125 rotated right by 4 becomes 5125C CS125 rotated right by 5 becomes CS125 C5125 rotated right by 8 becomes 125CS And so on. Notice how characters rotated off the right end of the String wrap around to the left. This problem is tricky! Here are a few hints: 1. You will want to use the Java remainder operator to perform modular arithmetic, so please review the remainder operator E. 2. You will probably want to convert the String to an array of characters before you begin. 3. You can convert an array of characters characters back into a string like this: new String(characters). 4. You can also solve this problem quite elegantly using substring, If the passed String argument is null, you should return null. Good luck and have fun
