You are given several boxes with different colors represented by different positive numbers.
You may experience several rounds to remove boxes until there is no box left. Each time you can choose some continuous boxes with the same color (i.e., composed of k boxes, k >= 1), remove them and get k * k points.
Return the maximum points you can get.

Example 1:
\n\n\nInput: boxes = [1,3,2,2,2,3,4,3,1]\nOutput: 23\nExplanation:\n[1, 3, 2, 2, 2, 3, 4, 3, 1] \n----> [1, 3, 3, 4, 3, 1] (3*3=9 points) \n----> [1, 3, 3, 3, 1] (1*1=1 points) \n----> [1, 1] (3*3=9 points) \n----> [] (2*2=4 points)\n\n\n
Example 2:
\n\n\nInput: boxes = [1,1,1]\nOutput: 9\n\n\n
Example 3:
\n\n\nInput: boxes = [1]\nOutput: 1\n\n\n
\n
Constraints:
\n\n1 <= boxes.length <= 1001 <= boxes[i] <= 100给出一些不同颜色的盒子 boxes ，盒子的颜色由不同的正数表示。
你将经过若干轮操作去去掉盒子，直到所有的盒子都去掉为止。每一轮你可以移除具有相同颜色的连续 k 个盒子（k >= 1），这样一轮之后你将得到 k * k 个积分。
返回 你能获得的最大积分和 。
