-## 📝 Instrucciones:
-
-1. Escribe una función llamada `getAverageOfElementsAtProperty`. Dado un objeto y una key, `getAverageOfElementsAtProperty`, retorna el promedio de todos los elementos en el array ubicado en esa key.
-
-## 📎 Ejemplo:
-
-```js
-let obj = {
-  key: [1, 2, 3]
-};
-let output = getAverageOfElementsAtProperty(obj, 'key');
-console.log(output); // --> 2
-```
-
-## 💡 Pistas:
-
-+ Si el array en esa key está vacío, debería retornar `0`.
-
-+ Si la propiedad en esa key no es un array, debería retornar `0`.
-
-+ Si no hay ninguna propiedad en esa key, debería retornar `0`.

 A palindrome is a text that reads the same backward as forward. For example, in the string `My dad is a racecar athlete`, the longest palindrome is `a racecar a` (*whitespaces count as valid characters*). Other palindromes in the above string include 'dad', 'ete', ' dad ' (including the whitespace on each side of dad).
