After learning Android for a while, I have been reading it all the time and have no attempt. Recently I learned how to use gridview with simpleadpter, so I want to practice it, you chose to write a simple calculator.
It only contains the +-*/four basic operations, but even such a simple small program has been done fo
Implement a basic calculator to evaluate a simple expression string.The expression string contains only non-negative integers,,, + - * , / operators and empty spaces . The integer division should truncate toward zero.Assume that the given expression was always valid.Some Examples:"3+2*2" = 7 "3/2" = 1 "3+5/2" = 5Note: don't use the eval built-in library function.Credits:Special thanks to @ts for adding this problem and creating all test cases.[Leetc

Preface
Hello, everyone. I have been studying the framework and background content for a while. To prevent front-end JavaScript and jq from being too skilled, I forgot many algorithms and basic usage, some small function effect codes will be updated in succession for record and accumulation. There are many deficiencies. encapsulation and code redundancy

Use string parsing to complete the design idea of the calculator and the design idea of the calculator
Statement:
A correct calculated string is in good format, such as: {ln (10) + 5 * [cos (2 π + 1/4 π) + sin (1 + 2 + 3 π)]}.
Computing is to associate or integrate a series of irrelevant data into a number, which is the meaning of computing.
Body:
As shown in the example, a correct calculated string contain
