## Problem Statement

#### For Example :

``````For 'N' =  5 and 'K' = 2

Let the cost of different candies in the store be: [9 8 2 6 4]

For the minimum amount:
Ram can buy a candy with cost 2 and take candies with costs 9 and 8 for free.
Then, he can buy a candy with cost 4 and take candy with cost 7 for free.
Thus, the minimum cost will be 6 i.e. 2 + 4.

For the maximum amount:
Ram can buy a candy with cost 9 and take candies with costs 2 and 6 for free.
Thus, the minimum cost will be 17 i.e. 9 + 8.

Thus, Minimum = 6 and Maximum = 17.
