refreshing, yes, a small function incredibly divided into three kinds of situations. Perhaps the last element should be treated differently, see the code below1#include 2 #defineN 53 intMainvoid)4 {5 intI, arr[n] = {1,2,3,4,5};6 for(i =0; I 1; i++)7printf"%d", Arr[i]);8printf"%d\n", Arr[n-1]);9 return 0;Ten}There's really a printf missing, only two cases. Can it be unified again? Note that the spaces and line breaks are characters and can be abstracted as follows:You want to pick a

Today, a friend from the group (Java Coder group: 91513074) asked me how to read the help documentation or solve the problem. I hope I can introduce my methods.In fact, this OneCoder is not qualified to talk about it. You can only talk about your habits and methods. Self-learning and self-solving are indeed a very important capability, far more important than the knowledge you have now, because you are always unknown.About API documentationSome people often ask for various API documents.

to wish someone a happy birthday, you might write code similar to the following:Birthday.pyage = 23message = "Happy" + age + "Rd birthday!" Print (message) Traceback (most recent call last): File ' birthday.py ', line 2, in This is a type error, meaning Python does not recognize the information you are using. In this example, Python finds you used a variable with a value of integer (int), but it does not know how to interpret the value (see). Python knowsThis variable may represent a value of 2

following, that is: The example here demonstrates only the type qualification of a generic method, with exactly the same rules for the restriction of type parameters in a generic class, just the header of the class declaration, such as:public class DemoFinally, it is emphasized that the most important function of generics is to improve the security of the code, because it is able to check the code at compile time, thus avoiding many exceptions that occur during the run-time strong-turn type. Un

have multiple generic parameters, separated by commas, and can also define generic interfaces, generic methods. These are similar to the usage rules for generics in generic classes.Multi-Interface RestrictionsAlthough Java generics simply use extends to represent the original concept of extends and implements, but still adhere to the application of the system, Java can only inherit one class, but can implement multiple interfaces, so you need to use a certain type of extends qualification, And

, such as you use Netty to develop, then will have a deeper understanding of TCP/IP. and the "Data structure and algorithm" This book, is more suitable for doing computational research work, such as the distributed computing just mentioned. In addition, I would like to emphasize that this is the right place, not the other two is not useful to you. For example, you do Java Web and app back-end development, "TCP/IP detailed volume one or two, three" this book on your role is also very big. This is

For example: Tuple1 = (' P ', ' y ', ' t ', ' h ', ' o ', ' n ')Set set for example: set1={' P ', ' y ', ' t ', ' h ', ' o ', ' n '}Dictionary dict For example: Dict1 ={1: ' P ', 2: ' Y ', 3: ' t ', 4: ' H ', 5: ' O ', 6: ' N '}What are the differences and effects of these data structures?
