VI function is the weakest, but also *nix fucked after the most basic Editor.Later VI was enhanced to include many features, which is vim.Then vim joined the graphics interface, Gvim was born.The strongest feature is Gvim, which has many features that Vim does not support, and VI does not supportFor example, do you want to enrich your colors? Blinking the cursor? Set the font independent of the terminal .... These are only gvim supported.Not rigorous said VIM is a collectively representative of

This topic, in the textbook, is generally required to use 51 single-chip microcomputer bit operation instructions to program, so, the answer should be used in assembly language.However, see most netizens, to the assembly is relatively dull, so, also put C language in here.
//==================================
Some netizens directly follow the logic diagram to write the program, no prior logic si
Do not perform the remove/add operation of elements in the Foreach loop. The remove element uses the Iterator method, which requires a lock on the Iterator object if the concurrency operation.
Positive example: iterator
while (Iterator.hasnext ()) {
String item = Iterator.next ();
If (delete element's condition) {
Iterator.remove ();
}
}
Counter example: list
List.add ("1");
List.add ("2");

The problem solving process is very elegant. The bitwise operation is used to maintain an optional character set combination, and the Union and intersection are completed.

container, you should think of a value assignment. If you just copy a container to another container of the same type, operator = is the selection assignment function, but for the example demonstrated, when you want to give a container a completely new data set, assign can be used, but operator = cannot.
The second purpose of this test is to demonstrate why interval member functions take precedence over their single-element member functions. OneInterval member functionsIt is a member function

The ISAPI arranges a new aspnet_wp.exe to handle the work. The main task of Aspnet_wp.exe is to give the request to a series of managed objects called the HTTP pipeline. If the ASP i
