difference between vi and vim

There is a shape array A, design an algorithm with a complexity of O (n), and calculate the maximum difference between two adjacent numbers after sorting.Given the size nof an int array a and a , return the maximum difference. The array element is guaranteed to be more than 1.Test examples:[1,2,5,4,6],5Returns: 2 Public classGap { Public intMaxgap (int[] A,intN) {//Write code here if(NULL= = A | | Nr

VI is an extremely popular full-screen document editor in the Unix world, and almost any UNIX machine will provide this software as a Notepad for Windows . Type vi/etc/hostsEnter the VI interface and move the cursor to the end of the file. Press ESC to make the command mode, then enter a, and a new line to enter the host you want to configure, such as: 192.168.0.

Click the ESC key, and then: Wq Save and Exit VI"VI is one of the most commonly used editors of the unix/linux system, and I am accustomed to using the": X "command to save the file and exit, and do not want to use the": Wq "command because it has to knock one more letter.But today I only know the real difference between ": X" and ": Wq", as follows:: Wq mandator

version and scope are read from the parent Pom; In addition, if a version number is specified in a subproject, the jar version specified in the subproject is used . 4.Maven convention is better than configuration it proposes this concept to provide a reasonable default behavior for the project without unnecessary configuration.

GetName () + "@" +integer.tohexstring (S.hashcode ());System.out.println (STR1);System.out.println (STR2);Output Result:[Email protected][Email protected]Note: We can think of the last six decimal digits as the memory address of this object, but it is not really the address value, but the object's hash code value, this hash code value by default is a number c

Vim is one of the most commonly used editors of the unix/linux system, and when I save a file, I usually choose ": Wq", because when I first learned vim, I only remembered a few commonly used commands, and there was no meaning of the scrutiny command.However, when I compiled the code recently, I found that, without modifying the source file, only the ": Wq" command is used to save the file, the source file

Excerpt from: http://www.apelearn.com/bbs/thread-7146-1-1.htmlThe differences between ": X" and ": Wq" are as follows:(1): Wq Mandatory Write file and exit (save and exit write and quite). Force write even if the file is not modified, and update the file's modification time.(2): x write to File and exit. Writes only when the file is modified and updates the file modification time, otherwise the file modification time is not updated.The two are generally not the same, but in terms of programming,
