String Rotate Left
Write a function called
rotateLeft that takes a
String as its first argument and a non-negative
its second argument and rotates the
String left by the given number of characters.
Here's what we mean by rotate:
CS125rotated left by 1 becomes
CS125rotated left by 2 becomes
CS125rotated left by 3 becomes
And so on.
Notice how characters rotated off the left end of the
String wrap around to the right.
This problem is similar to one that you have done before, but has a new wrinkle.
If the passed
String argument is
null, you should return
Good luck and have fun!
