1388\. Pizza With 3n Slices

Hard

There is a pizza with `3n` slices of varying size, you and your friends will take slices of pizza as follows:

*   You will pick **any** pizza slice.
*   Your friend Alice will pick the next slice in the anti-clockwise direction of your pick.
*   Your friend Bob will pick the next slice in the clockwise direction of your pick.
*   Repeat until there are no more slices of pizzas.

Given an integer array `slices` that represent the sizes of the pizza slices in a clockwise direction, return _the maximum possible sum of slice sizes that you can pick_.

**Input:** slices = [1,2,3,4,5,6]

**Output:** 10

**Explanation:** Pick pizza slice of size 4, Alice and Bob will pick slices with size 3 and 5 respectively. Then Pick slices with size 6, finally Alice and Bob will pick slice of size 2 and 1 respectively. Total = 4 + 6.

**Example 2:**

![](https://assets.leetcode.com/uploads/2020/02/18/sample_4_1723.png)

**Input:** slices = [8,9,8,6,1,1]

**Output:** 16

**Explanation:** Pick pizza slice of size 8 in each turn. If you pick slice with size 9 your partners will pick slices of size 8.

**Constraints:**

*   `3 * n == slices.length`
*   `1 <= slices.length <= 500`
*   `1 <= slices[i] <= 1000`
