								< 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 >
