题目如下: 解题思路:本题可以采用贪心算法,因为每条船最多只能坐两人,所以在选定其中一人的情况下,再选择第二个人使得两人的体重最接近limit.考虑到人的总数最大是50000,而每个人的体重最大是30000,因此会有很多人体重一样.这样可以用一个集合set保存体重,再用字典保存每个体重对应的人的数量,可以减少运算量.最后对set进行升序排序,再用双指针的方法,用low指针指向set头部,high指针指向set尾部,分别比较set[low]和set[high]的值,有如下情况: a. set[lo…

第 i 个人的体重为 people[i],每艘船可以承载的最大重量为 limit. 每艘船最多可同时载两人,但条件是这些人的重量之和最多为 limit. 返回载到每一个人所需的最小船数.(保证每个人都能被船载). 示例 1: 输入:people = [1,2], limit = 3 输出:1 解释:1 艘船载 (1, 2) 示例 2: 输入:people = [3,2,2,1], limit = 3 输出:3 解释:3 艘船分别载 (1, 2), (2) 和 (3) 示例 3: 输入:peopl…

题目 给你一根长度为 n 的绳子,请把绳子剪成整数长度的 m 段(m.n都是整数,n>1并且m>1),每段绳子的长度记为 k[0],k[1]...k[m] .请问 k[0]k[1]...*k[m] 可能的最大乘积是多少?例如,当绳子的长度是8时,我们把它剪成长度分别为2.3.3的三段,此时得到的最大乘积是18. 示例 1: 输入: 2 输出: 1 解释: 2 = 1 + 1, 1 × 1 = 1 示例 2: 输入: 10 输出: 36 解释: 10 = 3 + 3 + 4, 3 × 3 × 4…
