HackerEarth Hunger Games problem solution

In this HackerEarth Hunger Games problem solution, You have reached the final level of Hunger Games and as usual a tough task awaits you. You have a circular dining table and N hungery animals.You need to place them on the table.Each animal has a hunger value.

You can place the animals in any order on the circular table.Once you place them you need to calculate the Danger value of your arrangement.

The danger value of the arrangement is the maximum difference of hunger values of all the adjacent seated animals.You need to keep this danger value as low as possible.
