# Company Tour 2017 to Noland

## 2ndJLTi Code Jam – Apr 2017

Input: Capacity = 125, w = [45, 25, 80, 100, 125]

Explanation: This year, RC has taken all JLT Asia employees to Noland for the company trip. As the name implies there is not much land in Noland, it is river everywhere. When we have to cross such a river having only one boat with a certain capacity (in the above example 125 Kg), Warren Downey, our Deputy CEO approaches RC and asks us to quickly divide the people so that each trip of the boat carries people exactly to its maximum capacity, 125 Kg in this example. He shows the example above and works out the below output that he desires.

Output: {45, 80}, {25, 100}, {120}

When RC team pointed out what would happen for a scenario when we have a case like Capacity = 120, w = [40, 20, 80, 100, 120, 70]. Warren informs us we always utilize our resources to its maximum capacity. No compromise. We will not cross the river and will change the tour itinerary.

Output: No crossing, change itinerary.

Task: When I woke up an hour ago from my afternoon nap with a lot of stress, I realized that the tour was just a bad dream. I started feeling relaxed. But the problem got into my head and now it is itching everywhere inside it. In this situation, I realize, I can spread the itching to my JLTi friends in Singapore and Mumbai as well.

You can imagine there is a boatman and his weight is out of consideration. The input capacity is only applicable for the passengers. The input w array is holding only the passenger weights. In short, you can ignore the boatman.
