Given a String, return a String made of the chars at indexes 0,1, 4,5, 8,9, and so on. So "kittens" yields "kien".

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.

String altPairs(String input) {
  return ""; // You may need to remove this starter code
}
