Analysis: The minimum cut will certainly divide the original image into two point sets. One is the set of S that can be reached by the source point , and one is the T -set that can reach the meeting point (reachable is for the
Know that's unbounded wildcard setFacts about SetThere is facts about SetItem 1:since the question mark? stands for any type. SetItem 2:because we don ' t know the type of, we can ' t put any element into setSo a setItem 1 means the following situation:
Legal codepublic static void Main (string[] args) {hashset
Since setItem 2 means the following situation which is illegal:

1. Ordered Set: Elements in the set can be accessed by key or index. Unordered set: the elements in the set can only be traversed.An ordered set has good performance in adding, deleting, and modifying attributes.
2.Unordered set:

Background:
A long time ago (, articles were time-sensitive, especially when tools were frequently updated. Remember this time. If there is no value available, refer to the official tool documentation ), I have a new mysql version. The latest version is mysql5.7.18, and the local version is win10 and 64-bit. The general steps are as follows

Common Set Operations in Java and common set operations in Java1. Map value pairs are stored. Add the HashMap class of a common derived class:
Put (key, value) to add data to the setDelete:
Clear () delete all
Remove (key) to clear a single object. Find it based on k.Obtain:
Size () gets the number of elements
Get (key) obtains the data based on the key

When not using the router, the computer directly connected to the broadband Internet, now use the router sharing broadband Internet access, you need to use a router to directly connect broadband. According to the different broadband line in the household, can be divided into network cable, telephone line, optical fiber three kinds of access mode. Please refer to the following dynamic diagram for a specific connection:

The elements in set are unordered (the order in which they are deposited and taken out is not necessarily consistent), and the elements cannot be duplicated.The methods in set are the same as those in collection.Common sub-categories: HashSet TreeSetHashSet the underlying data structure is a hash tableTreeSet the underlying data structure is a two-fork treeImport java.util.hashset;import java.util.iterator;
Set set is a sequence of unordered, non-repeating elementsThe basic function is to test the membership and remove duplicate elements.Use the brace {} or set () function to create a collection, note: Creating an empty collection must be set () instead of {}, because {} is used to create a new dictionary.Add (): Increase

Set OverviewUnlike vectors and lists, set and map are associative containers. The set interior is based on the red and black tree. Insert and delete operations are more efficient because you only need to modify the relevant pointers without moving the data.After the data deletion operation, the iterator will not be invalidated. When you delete a set's data, the a
