C ++ STL has been widely praised and used by many people. It not only provides convenient containers such as vector, string, and list, more importantly, STL encapsulates many complex data structure algorithms and a large number of common data structure operations. Vector encapsulation array, li
As a network manager, I believe there are leaders who ask you to restrict your employees ' access to the Internet, such as restricting access to certain websites. When the number of banned sites is low, adding a URL set or a domain name set is a simple matter, if the number of banned sites up to 1500?

STL SetB add a meaning?The STL can look up this sequence, insert any element of the deleted sequence, and the time to complete these operations is proportional to the logarithm of the number of elements in the sequence, and when the cursor points to a deleted element, the delete operation is invalid. A corrected and more practical definition should be: A collection (set) is a container in which the values of the elements contained are unique. This is

The Disjoint set or Union-find set is a tree-type data structure. It is often used to process the merge and query of some Disjoint Sets.
There is a union-find algorithm that defines two operations for this data structure:

The set does not retrieve elements based on the index. to traverse and combine these elements, you cannot rely on a common for loop.
Only the iterator can be used to traverse a set, and the new loop can be traversed, because the implementation mechanism of the new loop also uses the iterator.

Due to historical reasons, Oracle had no Chinese character sets (such as oracle6, oracle7, and oracle7.1) in the early days. However, some users used databases since then and Stored Chinese characters with the us7ascii character set, or some users may choose a default character set, such as we8iso8859p1 or us7ascii, without any Chinese character encoding when creating a database, although this character

I. Introduction:
In the Tianyi programming language ranking in 18th, Swift ranked. Since the first release of the WWDC press conference, swift has been sought after by programmers for less than half a year, he is no less enthusiastic than Taylor Swift, the Red Star. I believe that in the near future, swift will be able to develop smoothly and gradually replace Objective-C.
