LeetCode ProblemEat Pizzas!
You are given an integer array pizzas of size n, where pizzas[i] represents the weight of the ith pizza. Every day, you eat exactly 4 pizzas. Due to your incredible metabolism, when you eat pizzas of weights W, X, Y, and Z, where W <= X <= Y <= Z, you gain the weight of only 1 pizza! Find the maximum total weight you can gain by eating all pizzas optimally. Note: It is guaranteed that n is a multiple of 4, and each pizza can be eaten only once.
