该文讲述了如何利用单调栈实现一个高效的算法,求解输入整数N的最大单调递增数字。该算法的时间复杂度为O(n),其中n是输入整数N的位数。该算法利用了单调栈的特性:当从左到右扫描数组时,如果栈顶元素等于当前遍历的元素,那么栈顶元素会保持不变;否则,栈顶元素会一直单调递减。因此,该算法只需要从左到右扫描一遍数组,即可找到最大的单调递增数字,并将其作为结果返回。

给定一个整数序列,找到最长上升子序列(LIS),返回LIS的长度。 说明最长上升子序列的定义: 最长上升子序列问题是在一个无序的给定序列中找到一个尽可能长的由低到高排列的子序列,这种子序列不一定是连续的或者唯一的。https://en.wikipedia.org/wiki/Longest_increasing_subsequence
这是我开始选择的方法,非常直白,但是直白简单的方法往往不是最佳的解法,提交到LeetCode上,给我抛出一个超时,可见效率有多低。首先写一个函数,判断一个数是否是符合要求的,如果不符合要求,就将这个数递减,直到找到符合的数为止,试想假如这个数是95555555555,那么符合题意的数是9,想想看要做多少次减法啊!!!!

本文提出了一种用于卫星图像中的小目标分割的模型,该模型使用一种混合空洞卷积来同时增加感受野和保持特征图分辨率。具体来说,该模型使用密集预测模块来提取特征,并使用空洞卷积模块来增加感受野。实验结果表明,该模型在卫星图像中的小目标分割任务上比现有的方法具有明显的性能提升。
这里采用深度优先的思路进行解决。先将数组按照从小到大排序,再从左往右遍历数组,每个数字有两种可能,分别是选中到子数组,或者不选中。将所有的结果收纳即可获得最终的结果集。
Given an unsorted array return whether an increasing subsequence of length 3 exists or not in the array.
借助命令lsort可对列表进行排序。该命令可提供多个选项,从而实现不同的排序方式。lsort接受一个列表作为参数,返回值为排序后的结果,默认情形下,返回的新列表按照-ascii-increasing顺序排序。例如:
Problem Description A DFS(digital factorial sum) number is found by summing the factorial of every digit of a positive integer.
给定一颗二叉搜索树,重新进行排序,使其根节点是最小值,且每个节点都没有左子树,只有一个右子树,最终还要保持该树是一颗二叉搜索树.
拐点检测(Knee point detection),指的是在具有上升或下降趋势的曲线中,在某一点之后整体趋势明显发生变化,这样的点就称为拐点(如图1所示,在蓝色标记出的点之后曲线陡然上升):

近期在处理视频编码的过程中,我遇到了一个错误:“Application provided invalid, non monotonically increasing dts to muxer in stream 0: -92233720368547”。这个错误消息可能会让人感到困惑,因此我在这篇文章中将解释这个错误的意义以及如何解决它。
Last_IO_Error: Got fatal error 1236 from master when reading data from binary log: 'The slave is connecting using CHANGE MASTER TO MASTER_AUTO_POSITION = 1, but the master has purged binary logs containing GTIDs that the slave requires. Replicate the missing transactions from elsewhere, or provision a new slave from backup. Consider increasing the master's binary log expiration period. The GTID sets and the missing purged transactions are too long to print in this message. For more information, please see the master's error log or the manual for GTID_SUBTRACT.'

1. 背景 在SRS使用中实现视频录制功能。 2. 思路 方案1:实时方式 拍照:操作者点击拍照按钮,触发网络请求,后端收到请求后启动一个ffmpeg 命令行进行截图。 录像:操作者点击开始录像按钮,触发网络请求,后端收到请求后启动一个ffmpeg 命令行录像,待操作者点击结束录像按钮后录像完成。 方案优点:容易实现 方案缺点:操作和响应的延时,即点击按钮后,约有2-5秒延迟(网络响应时间+ffmpeg启动时间+ffmpeg打开流时间+ffmpeg拍照响应时间。 争议:看到的视频的当前播放内容(时间) !
在卷积神经网络中,感受野(Receptive Field)的定义是卷积神经网络每一层输出的特征图(feature map)上每个像素点在原始图像上映射的区域大小,这里的原始图像是指网络的输入图像,是经过预处理(如resize,warp,crop)后的图像。
在做这道题之前,我们先来看一道它的简化版本300. Longest Increasing Subsequence,官网给出了两种解法,时间复杂度分别为O(n2)O(n^2)和O(nlogn)O(n \log n).

Given an increasing sequence S of N integers, the median is the number at the middle position. For example, the median of S1 = { 11, 12, 13, 14 } is 12, and the median of S2 = { 9, 10, 15, 16, 17 } is 15. The median of two sequences is defined to be the median of the nondecreasing sequence which contains all the elements of both sequences. For example, the median of S1 and S2 is 13.

Given a list of N student records with name, ID and grade. You are supposed to sort the records with respect to the grade in non-increasing order, and output those student records of which the grades are in a given interval.
如何在只做一次遍历就得到结果呢?因为结果只有三个元素,而且是按列表下标序递增变大,那么我的思路是用一个变量去存一次遍历中列表的最小值,如果遇到比它小的就做替换;这次遍历中如果遇到比现有的最小值大的,就把它存成次小值;如果之后还有比次小值更大的,说明这个满足题意的三元组一定存在。上述过程也是唯一一种存在该三元组的情况,其他则都返回False。
