Given a non-nullString and a intn, return a String made of n repetitions of the last n characters of
the passed string.
n will be between 0 and the length of the string, inclusive.
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.
StringrepeatEnd(Stringinput, intn) {
return""; // You may need to remove this starter code
