, the following code:Its output is:Note that all names are printed, and all uppercase names are printed with a length greater than 3. Why do you print alternately? This is because when the Foreach enumeration is started, the members of the uppercase are not sure, we run select first, Print the original, and then filter if the length is greater than 3, so the result is alternating between uppercase and Origi

This article is about the PHP surface of the question two of the use of the transmission protocol, has a certain reference value, now share to everyone, the need for friends can refer to 1.HTTP (Hyper Text Transport Protocol): Hypertext Transfer Protocol. It is one of the most widely used communication protocols on the Internet, and the WWW program used by internet users is required to abide by this Protocol standard. If a user wants to access a file

into two sub-arrays of length 2, and then the two sub-arrays are two sub-arrays of length 1 in Tea city. The next side merges adjacent sub-arrays, counting the number of reverse pairs. In the first pair of sub-arrays of length 1 {7},{5}, 7 is greater than 5, so {7,5} consists of an inverse pair. Similarly, in the second pair of sub-arrays of length 1 {6},{4}, there is also an inverse pair of {6,4}. Since we have counted the two pairs of sub-arrays in

pleasant little sister informed me to carry out 4 interview, Super Nice.Four:In an afternoon on the four sides, the interviewer is very serious, first let me talk about network programming, and let me talk about the Java EE, the interviewer a pair of what do not know, let me tell him to listen to the look, I feel he is not satisfied. Out of the also very confused force, can not say what is wrong, is feeling pretty bad.Sure enough to receive the rejec

The condition" 1. The color array corresponding to the vertex coordinate array and the vertex coordinate must be given. 2. The point, line, and plane are subclasses or grandchildren of geometryarray, so they inherit all its methods. 3. because geometry objects are all geometric objects, they cannot be placed in a 3D scene map separately, because only three-dimensional shapes can display three-dimensional effects, including vertices and lines, th

Distinction between Java and C ++ in terms of basic concepts of surface image objectsI. Introduction As we all know, C ++ and Java are two mainstream object-oriented languages today. Each person has their own opinions on the advantages and disadvantages of these two languages, the consensus is that C ++ is a compilation-type high-level language while Java is interpreted. Therefore, C ++ is fast and Java is compatible, C ++ is suitable for underlying c

The interview is something we all have to go through, most people and more than once, here to summarize the latest 2016-year interview questions, so that everyone in the search for work can be more effective.1.Switch can I use string to make arguments?A. Prior to Java 7, switch can only support Byte,short,char,int or its corresponding wrapper class and Enum type. In Java 7, String support was added.The difference between 2.equals and = =:a.== is to determine if two variables or instances are poi

(definitely =1) f[1] represents the number of numbers k in 00-99. F[2] represents the number of numbers k in 000-999....Existing formula: F[i] = f[i-1] * 9 + 10IG[1] Represents

Now the application of geo-information is very hot, whether it is from the location of Google map information, or through the iphone or Android, such as mobile terminals with GPS modules to obtain geographical information, are decimal latitude and longitude information. We may need to compute the distance between two points on the Earth's surface when we do the actual application, and here is the example language of JavaScript, which provides a comput

difference between non-repeatable reads and dirty reads is that dirty reads are dirty data that a transaction reads from another transaction, and non-repeatable reads the data submitted by the previous transaction.In some cases, non-repeatable reading is not a problem, for example, we query a data multiple times and of course the results are the result of the final query. However, in other cases, problems can occur, for example, the same data A and B in turn, the query may be different, A and B

compare the result sizes of different combinations? For example: You can compare the size of 445 and 454 to confirm the position of 4 and 45, because 454:445 is large, so 45 should be in the front. So you can sort all the elements in the array by comparing the two-digit method, and then stitch them together. Is this the way we can find the final answer?Interviewer AngleThis is a greedy algorithm problem, in general, will think of the first number of

and update the T2 every time we generate new ugly numbers. For times 3 and 5, the same T3 and T5 are present.Java Code Implementation:public int getuglynumber_solution2 (int index) {if (index Compared with the first idea, the second way of thinking does not need to do any calculation on the integer of the non-ugly number, so the time efficiency is obviously increased. However, it is also necessary to point out that the second algorithm needs an arra
