Given a non-nullString, return a version without the first 2 characters.
Except keep the first character if it is 'a' and keep the second character if it is 'b'.
The string may be any length.
For this problem we're expecting only a method.
Don't define a class, include modifiers like static or public, add import statements, or add code outside the method declaration.
StringdeFront(Stringinput) {
return""; // You may need to remove this starter code
