Course Introduction:Regular expressions are a powerful tool in Python, which can be used for various operations such as matching, searching, and replacing text. In computer science, regular expressions are used to easily parse arithmetic expressions into a computer-readable format. This article will introduce how to use Python regular expressions for arithmetic expression conversion. First, we need to understand the syntax rules of arithmetic expressions. Arithmetic expressions consist of operands and operators, for example: 2+4*5. In this expression, the numbers 2, 4, and 5 are

Course Introduction:Infix notation Java implementation observes a common calculation formula: 3+4*5. Of course we know that we should first calculate 4*5 and then add this result to 3 to get the final result. If it is a more complicated calculation: 3+4* ((5-6)/7+8), this will still not trouble us. As long as we remember that () has the highest priority, then */, and finally +-, it will be fine. The problem is, this is the usual infix notation. However, through algorithm analysis, such an expression requires a judgment of priority every time, so the running time should be O(N^2). When the expression is very long and complex, an algorithm more suitable for computers is needed to calculate it. Introduction to suffix notation Reverse Polish notation (ReversePolishnot
