Analysis and implementation of inverse Polish calculator


We have completed a reverse Polish calculator, which is required to complete the following tasks:

  1. Enter an inverse Polish expression (suffix expression) and use stack to calculate the result

  3. Thinking analysis
  4. Code complete
package  com.atguigu.stack ;


public static void main(String[] args) {
