Now programming is also to walk the door, but did not grasp the algorithm can only say that they are still laymen, so we began to work hard to learn the algorithm, now put their daily learning to share in here hope everyone can like, and I also want to organize my day of study and thinking,.Two-point lookup: You often need to look for a value in an array. If it's a good order then you can find it quickly. We consider the brute force search, that is a
This article describes a PowerShell command to use the first few files that occupy the largest space under a directory or disk (such as D disk). In other programming languages, this task may require large sections of code, and in PowerShell we only need one line.
When we find that a disk is out of space, as an administrator, we have to do some cleanup on the useless files on the disk. In the face of this work, we have to think about what is useless f

Given an array nums containing n + 1 integers where each integer is between 1 and N (inclusive), prove that at least one D Uplicate number must exist. Assume that there are only one duplicate number, find the duplicate one.
Note:You must the Modify the array (assume the array was read only). You must use only constant, O (1) Extra

The latter is better to do, from the coordinate map to see the direct r=mid can.The former will have a problem when a[mid]==a[r], it is not possible to determine the median position on the polyline, at this time degenerate into a linear search, so that l++. So the worst case scenario for this algorithm

binary FindAlso known as binary search. This lookup method requires that the data for the lookup table be stored in a linear structure, and that the data in the lookup table is ordered from small to large in a keyword.Binary lookup (binary lookup) is a simple and efficient search algorithm with a lookup length of up to ㏒2n+1 (the depth of the decision tree), an average lookup length of ㏒2 (n+1)-1, and a higher efficiency than the sequential lookup, but binary lookup can only be applied to sequen

Sometimes you may need to search for files with certain characteristics in the system (such as file permissions, file owner, file length, file type, and so on ). There may be many reasons for doing so. For security reasons or general system management tasks, it may only be necessary to find a file that does not know where it is stored.
FindBecause find has powerful features, it has a lot of options, most of which are worth taking the time to look at. Even if the system contains a network file system (NFS), the Find command works equally well in the file system as long as you have the appropriate permissions.When running a very resource-intensive find command, many people tend to put it in the b
Features:Searches for a file in the directory structure and performs the specified action. This command provides quite a few look-up conditions and is powerful.Syntax:Find start directory looking for conditional actionsDescription:The Find command starts with the specified starting directory, searches its subdirectories recursively, finds the file that satisfies the search criteria, and takes relevant action on it.The search condition provided by this

Use the name option: The file name option is the most common option for the Find command, either by using the option alone or with other options. You can use a file name pattern to match files, remembering to enclose the filename pattern in quotation marks.No matter what the current path is, if you want to find the file name in your root $home th

Parameters of the find command;
Pathname: directory path searched by the find command. For example, use "." To represent the current directory, and use "/" to represent the root directory of the system.-Print: The find command outputs matching files to the standard output.-Exec: The find command executes the shell co
Each operating system is composed of thousands of different types of files. There are system files, user files, shared files, and so on. Sometimes we often forget where a file is stored on the hard disk. Searching for a file in Microsoft's Windows operating system is quite simple. You only need to click "start"-"Search" on the desktop, and then you can find a file on the local hard disk in various ways, local Network, and even search for various files
