题目如下: 解题思路:这题把我折腾了很久,一直没找到很合适的方法,主要是因为有重复的数字导致结果会有重复.最后尝试用字典记录满足条件的序列,保证不重复,居然Accept了. 代码如下: class Solution(object): def findSubsequences(self, nums): """ :type nums: List[int] :rtype: List[List[int]] """ res = [] queue = []…

这种increasing xxx 题真是老客户了.. 本题麻烦点在于不能重复, 但是和之前的那些 x sum的题目区别在于不能排序的 所以.... 我还是没搞定. 看了一个Java的思路是直接用set来存最终结果去重;  不太清楚Java的set自带比较函数? 用cpp的话就要为vector<int>编写hash函数... cpp的方案有点特别, 每次递归的时候用一个哈希表记录有哪些数字已经用过了..很巧妙 class Solution { public: typedef vector<…

给定一个整型数组, 你的任务是找到所有该数组的递增子序列,递增子序列的长度至少是2.示例:输入: [4, 6, 7, 7]输出: [[4, 6], [4, 7], [4, 6, 7], [4, 6, 7, 7], [6, 7], [6, 7, 7], [7,7], [4,7,7]]说明:    1.给定数组的长度不会超过15.    2.数组中的整数范围是 [-100,100].    3.给定数组中可能包含重复数字,相等的数字应该被视为递增的一种情况.详见:https://leetcode.c…

Longest Increasing Subsequences 题目连接: https://www.codechef.com/SNCKPA16/problems/MAKELIS Description 大厨最近了解了经典的最长上升子序列问题.然而,大厨发现,虽然最长上升子序列的长度 是唯一的,但子序列本身却不一定唯一.比如,序列 [1, 3, 2, 4] 的最长上升子序列有两个:[1, 3, 4] 和 [1, 2, 4]. 大厨在这个方向上多做了些研究,然后提出了下面的这个问题: 给定 K,输出…

Given an integer matrix, find the length of the longest increasing path. From each cell, you can either move to four directions: left, right, up or down. You may NOT move diagonally or move outside of the boundary (i.e. wrap-around is not allowed). E…

Given an unsorted array of integers, find the length of longest increasing subsequence. For example, Given [10, 9, 2, 5, 3, 7, 101, 18], The longest increasing subsequence is [2, 3, 7, 101], therefore the length is 4. Note that there may be more than…
