题目如下: 解题思路:本题可以维护三个字典,dic_1保存没有组成序列的单元素,dic_2保存组成了包含两个元素的序列中的较大的元素,dic_3保存组成了包括三个或者三个以上元素的序列中的最大值.因为合法的序列至少要三个元素,解题的关键是要使得dic_2和dic_1的元素尽快满足条件.对于任意一个还没有加入字典的元素,加入字典的优先级从高到低排序分别是dic_2 > dic_1 > dic_3,即优先匹配dic_2,接下来匹配dic_1,再就是dic_3,如果三个都不满足,说明在目前条件下市落…

leetcode659. Split Array into Consecutive Subsequences 题意: 您将获得按升序排列的整数数组(可能包含重复项),您需要将它们拆分成多个子序列,其中每个子序列至少包含3个连续的整数.返回是否可以进行这样的拆分. 思路: 虽然是medium,但是我感觉有点难想= =. O(n)复杂度. dp. 先分开各种不同的序列.按如果间隔大于1就坑定是不同的序列.按此分开不同的序列以此简化问题. 然后处理连续的序列.连续的序列false的情况就是没有足够的数…

题目如下: 解题思路:本题和[leetcode]75. Sort Colors类似,但是没有要求在输入数组本身修改,所以难度降低了.引入一个新的数组,然后遍历输入数组,如果数组元素是是偶数,插入到新数组头部,否则追加到尾部. 代码如下: class Solution(object): def sortArrayByParity(self, A): """ :type A: List[int] :rtype: List[int] """ res =…
