Description

Compare y actualice el inventario almacenado en una matriz 2D con una segunda matriz 2D de una entrega nueva. Actualice las cantidades de artículos de inventario existentes actuales (en arr1 ). Si no se puede encontrar un artículo, agregue el nuevo artículo y la cantidad en la matriz de inventario. La matriz de inventario devuelta debe estar ordenada alfabéticamente por artículo. Recuerda usar Read-Search-Ask si te atascas. Trate de emparejar el programa. Escribe tu propio código.
