| # Reto #38: Las sumas | ||
| #### Dificultad: Media | Publicación: 25/09/23 | Corrección: 02/10/23 | ||
|
|
||
| ## Enunciado | ||
|
|
||
| ``` | ||
| /* | ||
| * Crea una función que encuentre todas las combinaciones de los números | ||
| * de una lista que suman el valor objetivo. | ||
| * - La función recibirá una lista de números enteros positivos | ||
| * y un valor objetivo. | ||
| * - Para obtener las combinaciones sólo se puede usar | ||
| * una vez cada elemento de la lista (pero pueden existir | ||
| * elementos repetidos en ella). | ||
| * - Ejemplo: Lista = [1, 5, 3, 2], Objetivo = 6 | ||
| * Soluciones: [1, 5] y [1, 3, 2] (ambas combinaciones suman 6) | ||
| * (Sin no existen combinaciones, retornar una lista vacía) | ||
