| ## Description
 | |
| <section id="description"> Tarea: <p> Cree una función, o muestre una función incorporada, para contar el número de apariciones no superpuestas de una subcadena dentro de una cadena. </p><p> La función debe tomar dos argumentos: </p> el primer argumento es la cadena a buscar, y el segundo una subcadena a buscar. <p> Debe devolver un número entero. </p><p> La coincidencia debe producir el mayor número de coincidencias no superpuestas. </p><p> En general, esto significa esencialmente coincidir de izquierda a derecha o de derecha a izquierda. </p></section>
