surface 3 vs surface 4

15, because of 1+2+3+4+5=4+5+6=7+8=15, so the result prints out 3 sequential sequence 1--5,4--6,7--8.With previous experience, we also consider using two tree small and big to represent the minimum and maximum values of the sequence respectively. First initialize the small to 1,big to 2. If the sequence from small to

programs that the colleague executes.How the 1.4java cross-platform is implemented.Java is implemented using the JVM. Java source code, the Java compiler has been mutated into Java bytecode. Class, execute Java bytecode, Javaz bytes are interpreted by the JVM as specific platform specific instructions and executed, different platforms have different JVMs, the mainstream platform provides the JVM, so Java bytecode can be interpreted on the mainstream platform to perform. This means that Java byt

Java.lang.Exception class are check-type exceptions, and all exceptions that inherit from RuntimeException are referred to as non-checked exceptions. You can also check out the next article to learn more about the differences between checked and non-checked exceptions.3) What's the similarities between NullPointerException and Arrayindexoutofboundexception in Java?This is not a very popular issue in Java exception interviews, but it can be seen at di

before interviewing a lot of enterprises, has not had time to summarize, today the interview encountered some of the classic topics listed, the answer will be added later, for everyone to learn:1, arc in weak and assign difference, respectively used in what scene, weak the realization principle is what?Weak property used to modify a weak reference, in the ARC environment, all weak pointers pointing to this object will be set to nil. Asssign relative to the pointer assignment, do not operate the

weights of the page. For the weight of the setting, the factors considered are: 1. Whether it belongs to a more popular site 2. Link length 3. Link to the page weight of the page 4. The number of times the page was pointed to, and so on. Further consideration, for the popular site, can not be unlimited crawl, so need to carry out two level scheduling. When you first schedule which Web site to crawl, and th

collection classes provide a function of content traversal through the Java.util.Iterator interface. These interfaces allow iterating over the collection of objects. Manipulate each element object in turn. When iterators is used, a collection snapshot is included when the iterator is obtained. It is usually not recommended to modify the collection province when traversing a iterator.3. What is the difference between iterator and listiterator?Iterator

Step 1 Define the area of the water according to the perspective. Step 2 Creates a new layer, uses the Rectangular marquee tool (M) to select the area of the water, and fills it with any color. Step 3 Use the Layer Mask or eraser tool to expose the Brick column section. We will use this layer as a clipping layer. Step 4 Copy (CTRL+J) the background layer and clip i

After saying good-bye to the kitten, the broadband went into my computer. At the same time as the speed of the increase, the immediate problem is immediately placed in front of: The kitten had not slept before the things down, now a few minutes can be done. So, start to go crazy at an unprecedented speed to plug things into the hard drive, movies, games, music, software, and so on ... Within a few days, hard disk space began to get out. There is no way to see the end and will not be able to lose

no possibility of the 0 to the reciprocal, if the 0 for the countdown to do? When base bases are 0 and the exponent is negative, we do not do special processing, we will find the countdown to 0 to cause the program to run an error. How do you tell the caller of the function that this error has occurred? Exceptions can be thrown in Java to resolve.Finally, it should be pointed out that since 0 of the 0 are mathematically meaningless, so whether the output 0 or 1 are acceptable, but this needs to

a virtual table that has the same functionality as a physical table. The view can be increased, changed, checked, manipulated, views are usually a subset of rows or columns that have a table or multiple tables. Changes to the view do not affect the base table. It makes it easier for us to get data, compared to multiple table queries.Usage Scenarios for Views:Only exposes part of the field to the visitor, so build a virtual table, which is the view.Query data from different tables, and responden

Nine Chapters count judges Net-original websitehttp://www.jiuzhang.com/problem/51/TopicsDesign an algorithm to serialize and deserialize a binary tree.Explanation: Serialization means that some specific structure in memory becomes a string of formatted information. For example, for a linked list, we can serialize a list of 1->2->3->null such as "All-in-a-kind." For serialization algorithms, deserialization must be supported, and in the agreed format,

correctly, the result is persisted in the database, and the transaction results are saved even if there are other failures after the transaction commits. 10.
