【leetcode】553. Optimal Division

题目如下:

解题思路:这是数学上的一个定理。对于x1/x2/x3/..../xN的序列,加括号可以得到的最大值是x1/(x2/x3/..../xN)。

代码如下:

class Solution(object):
    def optimalDivision(self, nums):
        """
        :type nums: List[int]
        :rtype: str
        """
        if len(nums) == 1:
            return str(nums[0])
        elif len(nums) == 2:
            return str(nums[0]) + ‘/‘ + str(nums[1])
        res = ‘‘
        for i,v in enumerate(nums):
            if i == 0:
                res = str(v)  + ‘/‘ + ‘(‘
            else:
                res += str(v)
                res += ‘/‘
        return res[:-1] + ‘)‘

【leetcode】Minimum Window Substring

问题: 给定两个字符串,S,T,返回S中包含T中所有字符的最短的字串,若不存在,则返回"".时间复杂度为O(n). 例如:S = "ADOBCODEBANC" T = "ABC" 返回BANC 生活场景: 把问题具体化现实化一点.有n层楼,每层楼里放有一个物品,现在老板给你一个物品清单,里面是要你集齐的物品,你可以乘坐电梯,但是电梯只停一次,停在哪一层,就从哪一层开始向楼上搜集物品,至于要在那层停电梯,由你自己选择. 这里我们当然选择即能集齐物品

【leetcode】Generate Parentheses

题目: 给定整数n,返回n对匹配的小括号字符串数组. For example, given n = 3, a solution set is: "((()))", "(()())", "(())()", "()(())", "()()()" 分析: 这种问题的模式是:1)问题的解有多个 ,2)每个解都是由多个有效的 "步骤" 组成的,3)变更以有解的某个或某些"步骤"

【LeetCode】Copy List with Random Pointer

A linked list is given such that each node contains an additional random pointer which could point to any node in the list or null. Return a deep copy of the list. 思路:第一遍正常复制链表,同时用哈希表保存链表中原始节点和新节点的对应关系,第二遍遍历链表的时候,再复制随机域. 这是一种典型的空间换时间的做法,n个节点,需要大小为O(n

【leetcode】Max Points on a Line (python)

给定一个点,除该点之外的其他所有点中,与该点的关系要么是共线,要么就是共点,也就是两点重合. 共线有三种情况:水平共线,垂直共线,倾斜的共线.合并下这三种情况就是斜率存在的共线和斜率不存在的共线. 那么我们的任务就是针对每个点,找出与其共线的这些情况中,共线最多的点的个数. 注意:最终的结果别忘了加上共点的个数. class Solution: def maxPoints(self, points ): if len( points ) <= 1: return len( points ) ma

【LeetCode】 Maximum Subarray

Find the contiguous subarray within an array (containing at least one number) which has the largest sum. For example, given the array [−2,1,−3,4,−1,2,1,−5,4], the contiguous subarray [4,−1,2,1] has the largest sum = 6. More practice: If you have figu
