The higher the ERD version, the better. ERD: urgent disk repair, also known as the startup CD of MSDaRT. MSDaRT: Microsoft diagnostic and recovery tool set that helps diagnose and fix systems with startup failures or other problems. This is one of the Free Microsoft desktop optimization pack tools. One of them is called DaRT. Different versions are divided into two platforms: x86 and x64. 6.5: corresponds

interface is not friendly, and the operation steps are too complex. For general users, a string of English strings is often overwhelmed. Is there a better way to easily change the system logon password? The answer is yes. ERD Commander 2003 is a foolproof software that allows you to easily change the password of a system administrator. It is also effective for Windows 2000/XP/2003 systems. The following describes the usage of this software. 1. Downlo

Why should we understand the efficiency of the algorithm?In general, programming is to solve the problem by substituting various known algorithms into their own code. Therefore, understanding the efficiency of various algorithms is very helpful for us to choose a suitable algorithm.What determines the efficiency of the algorithm?From the theory of algorithmic analysis, the efficiency of the algorithm is usually evaluated by their complexity, which is indicated by the asymptotic

A singleton pattern is very much written. First, the most basic way to write:(a type of notation):Package Singleton;public class Singletoninstance {private static singletoninstance msingletoninstance = null;// Deliberately set the constructor to private to prevent external user new singletoninstance (). Private Singletoninstance () {}public static singletoninstance getinstance () {if (msingletoninstance = = null) { Msingletoninstance = new Singletonin

The single-instance pattern is written in a number of forms, giving the most basic form:(a type of notation):Package Singleton;public class Singletoninstance {private static singletoninstance msingletoninstance = null;// Deliberately set the constructor to private to prevent external user new singletoninstance (). Private Singletoninstance () {}public static singletoninstance getinstance () {if (msingletoninstance = = null) { Msingletoninstance = new

Polish notation, also called prefix notation. When calculating a polish expression, you only need to find the operator of the first operation without remembering the operation hierarchy. Take the binary operation as an example. Read the expression from left to right. When an operator follows two operands, it is calculated and the result is replaced by the operator and two operands as the operand; repeat th

Evaluate the value of an arithmetic expression in reverse Polish notation. Valid operators are+,-,*,/. Each operand may be an integer or another expression. Note: Division between two integers shoshould truncate toward zero. The given RPN expression is always valid. That means the expression wocould always evaluate to a result and there won't be any divide by zero operation. Example 1: Input: ["2", "1", "+", "3", "*"]Output: 9Explanation: ((2 + 1)
