Solve: Prefix Again

/ Adapted from CodingBat

Given a non-null String, consider the prefix made of the first n characters. Return true if that prefix string appears somewhere else in the string. Assume that the String is not empty and that n is between 1 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.

boolean prefixAgain(String input, int n) {
  return false; // You may need to remove this starter code
}
