Question Link Question: I will give you a string, but the space is lost. How many operations do you need to perform to make this string a legal inverse Polish style, for example, 12*3*4 is not a legal inverse polish type, but 12*34 * can be regarded as 1 2*34 * as a correct inverse polish type. Idea: when the number of numbers is more than the number of operators, it is obvious that the number of operations for the exchange is less. You just need to change the operator to the end. The implied me

There are two methods of jquery core:1, $.extend (object) can be understood to add a static method for jquery.2. $.fn.extend (object) can be understood to add a method to a jquery instance.Basic use$.extend ({ function() { alert (one); } }) $.fun1 (); $.fn.extend ({ function() { alert (); } }) $ (this). fun2 (); // equivalent to function () { alert; } $ (this). FUN3 ();The difference between jquery (function ()

"}; Request. Content = new ObjectcontentIv. reconstructionYou can see that most of the code for both tests is the same and is used to send requests. So we extract a webapitestbase class that can provide methods such as Invokegetrequest,invokepostrequest,invokeputrequestPublic abstract class Apitestbase {public abstract string getbaseaddress (); Protected TResult invokegetrequestWith this base class, we just need to rewrite the method getbaseaddress () and then call the base class meth

Evaluate the value of an arithmetic expression in Reverse Polish Notation.Valid operators is + , - , * , / . Each operand is an integer or another expression.Some Examples: ["2", "1", "+", "3", "*")--((2 + 1) (3)-9 ["4", "", "5", "/", "+"], 4 + (13/5))Stack only saves numbers, encounters operator, pops two numbers, calculates them, and then deposits the results in a stack. The first element of the last stack is the answer.Note-the difference from/to the first pop value is on the right side of

How can we convert a 4-byte number into hexadecimal notation? I only know the dechex function, but the transfer is Echo dechex (1407401322869 ); Afa7e975 The result of the four-byte calculator is 147afa8260. How can I implement it using PHP? Reply to discussion (solution) What is your calculator?It should be 147AFA7E975 Echo base_convert (1407401322869, 10, 16); // 147afa7e975 You have a problem with the calculator. No, modera
