1388. Pizza With 3n Slices

Leetcode Solutions

Define a function solve that takes a subarray of slices and the number of slices to pick.
Initialize three arrays: prev, curr, and next, each with a length of n+2 where n is the number of slices.
Iterate over the slices in reverse, updating the prev array with the maximum sum for each state.
For each slice, calculate the maximum sum by either taking the slice and adding the sum from next two steps ahead, or not taking the slice and taking the sum from curr one step ahead.
After processing each slice, rotate the arrays: next becomes curr, and curr becomes prev.
Repeat steps 3-5 for both cases: excluding the first slice and excluding the last slice.
Return the maximum sum obtained from both cases.
