LeetCode ProblemMinimum Cost for Cutting Cake II
There is an m x n cake that needs to be cut into 1 x 1 pieces. You are given integers m, n, and two arrays: In one operation, you can choose any piece of cake that is not yet a 1 x 1 square and perform one of the following cuts: After the cut, the piece of cake is divided into two distinct pieces. The cost of a cut depends only on the initial cost of the line and does not change. Return the minimum total cost to cut the entire cake into 1 x 1 pieces.
