Title Description: Again to the harvest season, coincides with the small easy to go to cattle and cows in the orchard to play. New often said he knew every place in the orchard, small easy to believe, so he wanted to test cattle and cattle. There are n stacks of apples in the orchard, and the number of apples per heap is AI, and it is easy to know which stacks of x apples are left to right. Niuniu thought this was a big problem, so I hope you did, he

cases, the connection will be in a close_wait state for a long period of time. There is a large number of close_wait, the main reason is that in some cases the other side closed the socket connection, but we are busy reading or writing. Do not close the connection, the code needs to determine the socket, once read 0, disconnect, read return negative, check the errno, if not again, disconnect.11, Time_waitThe active shutdown of the socket will enter this state, and the duration of 2MSL (maximum

Written Test interview 3 Splits a number into a prime factor form and how to determine whether a number is a prime number Although I have already found an internship and offered an offer, I decided to brush up some simple questions. These questions are only suitable for beginners who want to learn slag-level algorithms. Splits a number into a prime factor, for example: 10 = 2*5 100 = 2*2*5*5 In fact, the i

Summary:The recent enterprise online written test, found that most of the enterprise's written test platform using the game Code network (although a lot of slots), and on-line programming needs to use scanner to read the input of the program, therefore, the author on the achievements of the ancestors of scanner did a n

After I continued to update my job, I found there was another thing I could write (Haha, I like to write about East and West ). I can record some technical questions I have not answered or answered. Easy to learn. In this written test, the job is a test engineer, but the question seems to be a software engineer. Let's just review what I don't remember ~ In fact,

In the written test, I think many people will encounter factorial programming questions. Today, I suddenly remembered my first written test. I encountered such a question, but I haven't typed it on my computer. I just want to write it. I don't know if everyone has done the right thing during the

objects of this class are used in a multithreaded environment, it is best to use StringBuffer. 39. How do I convert a comma-delimited string into an array? Reference: (1) with regular expressions, the code is roughly: ' string[] result = Orgstr.split (","); ' (2) with StringTokenizer, code:StringTokenizer Tokener = StringTokenizer (Orgstr, ",");String[] result = new String[tokener.counttokens ()];int i = 0;while (Tokener.hasnext ()) {result[i++] = Tokener.nexttoken ();}40. 数组有没有length()方法？Strin

of the class, easy to handle exceptions;Development experience:The exception is the main processing of reading files, but also can be used with the method of reading files; can also be used for network connections where exceptions can include a large number of error messages for error handling.Code:Class Shortinputexception (Exception): def __init__ (self, length, atleast): exception.__init__ (self) self.length = length self.atleast = atleast while True: try:

database is that no matter how long your string contains, its sizeof () is fixed, and the space occupied by the string is dynamically allocated from the heap, regardless of sizeof.Sizeof (string) = 4 may be one of the most typical implementations, but there are also library implementations where sizeof () is 12 and 32 bytes. However, after the VC6.0 test, sizeof (string) = 16. It is still related to the compiler. 10. The answer to this question on p

, template definitions, and so on to a header file, the corresponding header file to be used in the #include包含到源文件 (*.cpp file). However, it is possible to include other header files in the header file, which will inevitably occur when a header file is repeatedly included. We can use the compile preprocessing command to avoid this situation. For example, if you want to make sure that the header file max.h not be duplicated, you can take the following form:The first preprocessing command is to sa

One problem encountered during the written test: design a class so that it can only allocate memory space on the stack. At that time, it was hard to get stuck and speechless. I personally feel like using the following method. Http://blog.csdn.net/daeees/archive/2010/07/18/5744225.aspx Sometimes, to ensure that the object of a class must be created on the stack, for example, when we need to manually cont

I took part in Hulu's test on Friday. I had a lot of questions in 70 minutes and I was not prepared enough. It took 40 minutes for the first 10 multiple choice questions, the last five blank questions had to be left blank. In this case, the time is not enough. The subjects are basic algorithms, data structures, and simple reasoning. Or its own reasons. The following algorithm questions are also very basic. Big integer addition (you can compare the big

There is an array of integers, please find out the number of K large in the array according to the idea of quick sorting.Given an integer array a, given its size n and the K (k between 1 and N) to be found, return the number of K to ensure that the answer exists.Test sample: [1,3,5,2,2],5,3Returns: 2My first idea is to sort by using a quick line, and then you can get the K max number after sorting. int quicksort (VectorI feel no problem, but I always get the right result. And the example gives
