Burst Balloons (Medium) 这题没有做出来. 自己的思路停留在暴力的解法, 时间复杂度很高: 初始化maxCount = 0. 对于当前长度为k的数组nums, 从0到k - 1逐个选取第i个气球扎破 计算扎破气球得到的金币数, count = nums[i - 1] * nums[i] * nums[i + 1]. 从nums中删掉nums[i]. 查询m[nums]是否存在, 不存在则递归调用maxCoins(nums)并插入m[nums]. count += m[num…

［抄题］: There are a number of spherical balloons spread in two-dimensional space. For each balloon, provided input is the start and end coordinates of the horizontal diameter. Since it's horizontal, y-coordinates don't matter and hence the x-coordinate…

现有 n 个气球按顺序排成一排,每个气球上标有一个数字,这些数字用数组 nums 表示.现在要求你戳破所有的气球.每当你戳破一个气球 i 时,你可以获得 nums[left] * nums[i] * nums[right] 个硬币. 这里的 left 和 right 代表和 i 相邻的气球的序号. 注意当你戳破了气球 i 后,气球 left 和气球 right 就变成了相邻的气球.求所能获得硬币数量的最大值.注意:(1) 你可以认为 nums[-1] = nums[n] = 1,但注意它们不是真…
