Cargo Ship
--------------------------------------------------------
You have to transport a maximum of 15 different loads from one port to another. Carrying capacity of a cargo ship, which will transport those loads, is 50 tons. Loads are enumerated and the information about the weight of every load is given as input.
Suppose that the weight of every load is smaller than or equal to 50 tons and greater than 0.
You will read the weight of every load from the input in a single line. Your input will end with a -1. You will print the number of trips necessary.
