The author in the use of WPS text editing documents, often need some data for simple accounting, in order to calculate the convenience, the author after some groping, trying to the WPS text in the Common toolbar added a calculator button, need to do data operation when the mouse can bring up the Windows system from the calculator ( As shown in Figure 1), thus significantly improving productivity.
First, the algorithm
1, the main idea of the algorithm is to convert an infix expression (Infix expression) into a convenient suffix expression (Postfix expression), and then with the help of the stack of this simple data structure, to calculate the results of the expression.
2, on how to speak the ordinary expression to the suffix expression, and how to deal with the suffix expression and calculate the results of the specific algorithm description is not described here, the book has a detaile
