In a parallel universe called Marvel, an infectious viral disease has been spreading at a very fast rate. Dr. Strange Is trying to create a potion that would prevent people from catching the disease and would also cure the ones already diseased.
He knows that the cure is a potion which is a mixture of N chemicals and is K liters in volume. He does not know the amount of each chemical that must be added and hence is experimenting on the same.
As the assistant of Dr. Strange, you help him in his task and ask him how to prepare the potion, to which he replies:
- Chemicals must be added in the increasing order of their labels.
