1. Simple arithmeticAlgorithm: For example, 1X2 + 3/3x4 + 8 The arithmetic above is relatively simple, with no parentheses. It is just a general operation. Now the only thing we need to do is to figure out the priority. In addition to the data structure, we can implement the stack assistant. The basic algorithm is as follows: there must be two stacks, one for data storage, and the other for operators. I
