The idea is very simple, you can read it. Import java.util.*; Class Max {static int a,b,c,d,e,f,g,h,i,j; public static void Main (string[] args) {int[] num=new int[100]; Random rd=new Random (); for (int n=0;n There is also a more technologically advanced solution that can solve similar problems. The following program provides two traversal methods for your reference. The idea is also very simple, using the HashMap, the array elements in tur

The question is selected from the following blog website:Http://zhedahht.blog.163.com /#. Question 26th:Question: enter a positive number N, and output all sequences that are n continuous positive numbers. For example, input 15, because 1 + 2 + 3 + 4 + 5 = 4 + 5 + 6 = 7 + 8 = 15, therefore, three consecutive sequences 1-5, 4-6, and 7-8 are output. Analysis: This is Netease's interview question. My o

1. Find two numbers that appear only once in the array. 1) Question: Except for two numbers in an integer array, other numbers appear twice. Write a program to find the numbers that appear only once. RequirementsThe time complexity isO (N),The spatial complexity isO (1) For example: A [] = {, 3,}; you need to find 5 and 6 2) analysis: the nature of an exclusive o

Java Basics1. What are the features of object orientation?1. Abstraction:Abstraction is to ignore those aspects irrelevant to the current target in a topic, so that you can pay more attention to the aspects related to the current target. Abstraction is not intended to understand all the problems, but to select a part of the problem. Abstract: Process abstraction and data abstraction.2. Inheritance:Inheritance is a hierarchical model that connects clas

Question 21st: Enter two integers, N and m, from the series 1, 2, 3 ....... N returns a few random numbers to make it equal to M. All possible combinations must be listed. When I saw such a question, I had no idea where to start. By collecting information online, I finally got it done. Let's take a look at the following ideas: Given N and m;1. Determine N * (n + 1
