running result is exactly as expected and proves the correctness of this algorithm. The Code is as follows: using System;using System.Collections.Generic;using System.Linq;namespace Evaluate{ class Program { static void Main(string[] args) { string testExpress = "(1+((2+3)*(4*5)))"; Console.WriteLine(Evaluate(testExpress)); } //DijkStra static

1. Requirement AnalysisDesign a program to demonstrate the process of using the operator priority method to evaluate an arithmetic expression. The operator precedence is used to evaluate the arithmetic expression. (1) Input Format: expression, for example, 2*(3 + 4) The contained operators can only include '+ ','-','*','/','(',')'; (2) form of output: calculation result, for example, 2*(3 + 4) = 14; (3) fun

We only know that the soft text is effective, the concept of this effect is rather vague. Many people have been said to be digitized to evaluate the effect of SEO, soft wen also do not need to be digitized to evaluate its effect? So what can we evaluate? 　1, reprint rate Only after the soft text is reproduced, its effect can be said to be maximized. But there

Abstract:This paper starts from the related concepts of software quality, and puts forward the selection principles of corresponding software quality evaluation indicators based on the analysis of software quality characteristics, then, a software quality evaluation system is established. Keywords: Software Quality Evaluation Index System 1. concepts related to software qualitySoftware Quality is the sum of features and features related to the ability of software products to meet defined or impl

I am often asked this question: How can I evaluate the security of a software system? One answer is: do we have specialized software security evaluation standards and institutions? Yes, we have specialized international standard common criteria, ISO/IEC 15408, and National Standard GB 18336. There are specialized evaluation centers, such as common criteria lab and China Information Security product evaluation and certification centers. It seems that w

An expression consists of parentheses, operators, and operands (numbers. In the following 4 cases, these entities are sent to the stack one by one from left to right. (1) Push the operand to the operand stack; (2) Push operators into the operator stack; (3) Ignore the left parenthesis; (4) In case of right parenthesis, an operator is displayed, a required number of operators are displayed, and the operation results of operators and operators are pushed to the operand stack. Dijastra's two-Stack
