There are 3n piles of coins of varying size, you and your friends will take piles of coins as follows:

\n\n\n\n

Given an array of integers piles where piles[i] is the number of coins in the ith pile.

\n\n

Return the maximum number of coins that you can have.

\n\n

 

\n

Example 1:

\n\n
\nInput: piles = [2,4,1,2,7,8]\nOutput: 9\nExplanation: Choose the triplet (2, 7, 8), Alice Pick the pile with 8 coins, you the pile with 7 coins and Bob the last one.\nChoose the triplet (1, 2, 4), Alice Pick the pile with 4 coins, you the pile with 2 coins and Bob the last one.\nThe maximum number of coins which you can have are: 7 + 2 = 9.\nOn the other hand if we choose this arrangement (1, 2, 8), (2, 4, 7) you only get 2 + 4 = 6 coins which is not optimal.\n
\n\n

Example 2:

\n\n
\nInput: piles = [2,4,5]\nOutput: 4\n
\n\n

Example 3:

\n\n
\nInput: piles = [9,8,7,6,5,1,2,3,4]\nOutput: 18\n
