Qiu zongyan: Evaluate expressions in C/C ++I often see the following questions in some discussion groups: "Who knows what value the C statement assigns to n ?"M = 1; n = m ++ M ++;Recently, an unfamiliar friend sent me an email asking why two 4 expressions are printed in a C ++ system, instead of four and five:A = 4; cout C ++ is not a rule To understand this, you need to understand the following problem: If a variable is modified somewhere in the Pro

Evaluate the value of an arithmetic expression in reverse Polish notation. Valid operators are+,-,*,/. Each operand may be an integer or another expression. Some examples: ["2", "1", "+", "3", "*"] -> ((2 + 1) * 3) -> 9 ["4", "13", "5", "/", "+"] -> (4 + (13 / 5)) -> 6 Solution: public class Solution { public int evalRPN(String[] tokens) { if(tokens==null) return 0; Stack Note: Determine if it is a number: 1 private bo

represent the affine transformation matrix. M1, m2, m3, and m4 indicate the scale and rotation characteristics. tx indicates the translation in the x direction and ty indicates the translation in the y direction. Then the coordinates of a matching point can be written Or write it Where (x, y) is before transformation, (u, v) is the coordinate after transformation. To understand how to evaluate the affine transformation parameters, perform the foll

Evaluate Reverse Polish Notation, evaluatenotation Original question link: https://oj.leetcode.com/problems/evaluate-reverse-polish-notation/ Question: Give the inverse Polish style and then ask for the result. Solution: Single stack Idea: traverse the inverse Polish formula. If it is a number, it is written into the stack. If it is an operator, two elements at the top of the stack will pop up, and then the

There may be more than one expression in tbindingslist. The Evaluate Method of the expression can be used to submit and bind separately, and can be submitted when active is set to false. The corresponding method in tbindexpritems is evaluateformat. Test idea: the binding source of label1 and label2 is edit1, and the binding is submitted separately. 1. Add controls to the form: label1, label2, edit1, and bindingslist1;2. Activate the onkey

Tags: prefix expression evaluate Link: http://pat.zju.edu.cn/contests/ds/3-07 Arithmetic expressions include prefix, infix, and suffix. Prefix expression indicates that a binary operator is located before two arithmetic operations. For example, the prefix expression of 2 + 3 * (7-4) + 8/4 is ++ 2*3-7 4/8 4. Please design a program to calculate the result value of the prefix expression. Input format description: Enter a prefix expression of no more t
