Pancake flipping in JavaYou have a stack of n pancakes of varying sizes on a griddle. Your goal is to rearrange the stack in descending order so that the largest pancake is on the bottom and the smallest one is on top. You are only permitted to flip the top k pancakes, thereby reversing their order. Devise a scheme to arrange the pancakes in the proper order by using at most 2n - 3 flips.
