addition

问题 I've got code for a binary addition console application which basically adds up two added binary numbers. could someone either explain to me how it works or write comments with the code to show how each part works. P.S All i don't understand is the function Heres the code: Dim a As Integer = 8 Dim b As Integer = 2 Dim c As Integer = 10 Sub Main() Dim binary1 As Integer Dim binary2 As Integer Console.WriteLine("---------------------BINARY ADDITION---------------------") Console.WriteLine(

问题 This question already has answers here : Closed 7 years ago . Possible Duplicate: How to Add a row vector to a column vector like matrix multiplication I have a nx1 vector and a 1xn vector. I want to add them in a special manner like matrix multiplication in an efficient manner (vectorized): Example: A=[1 2 3]' B=[4 5 6] A \odd_add B = [1+4 1+5 1+6 2+4 2+5 2+6 3+4 3+5 3+6 ] I have used bsxfun in MATLAB, but I think it is slow.

问题 im scratching my head with this one, I can do the usual contents of div + contents of another div addition in jquery, but im not sure how I go about adding together the contents of all instances of a particular span on a page. Basically I can a page that pulls info into it using jquery and ajax, it pulls in invoices for the month selected and displays them in each row. What I want to do is add off the the rows together with the class 'grandtotal', so I can display the monthly invoice total

问题 I'm not sure how else I could have framed my question, but I have a table with multiple header rows and their respective sub-rows. The sub-rows should add up and set the value of the header rows. How can I do this efficiently? <table> <tr> <td>A</td> //header row <td><input type="text"/></td> </tr> <tr> <td>A1</td> //sub-row <td><input type="text"/></td> </tr> <tr> <td>A2</td> //sub-row <td><input type="text"/></td> </tr> <tr> <td>B</td> //header row <td><input type="text"/></td> </tr> <tr>

问题 lets say you want to make a program that will print the numbers 1-9 over and over again 123456789123456789123456789 i guess the most obvious way to do it would be to use a loop int number = 1; while(true) { print(number); number = number + 1; if(number > 9) number = 1; } before i go any further, is this the best way to do this or is there a more common way of doing this? 回答1: The most obvious way would be this: for (;;) { for (int i = 1; i < 10; ++i) { print(i); } } Why you'd want to

问题 type Dictionary = [(String, String)] dict :: Dictionary dict = ("Deutsch", "English"):[] insert :: Dictionary -> (String,String) -> Dictionary insert dict entry = dict ++ [entry] One thing that I didn't find about the way lists work: Is it somehow possible to overwrite the existing dict with the entry added in insert? Or is it necessary to, in the next step, always write out the list that was put out by insert? insert [("German", "English"), ("Hallo", "hello")] ("Versuch", "try") So far, this

问题 How to design an algorithm to simulate multiplication by addition. input two integers. they may be zero, positive or negative.. 回答1: def multiply(a, b): if (a == 1): return b elif (a == 0): return 0 elif (a < 0): return -multiply(-a, b) else: return b + multiply(a - 1, b) 回答2: some pseudocode: function multiply(x, y) if abs(x) = x and abs(y) = y or abs(x) <> x and abs(y) <> y then sign = 'plus' if abs(x) = x and abs(y) <> y or abs(x) <> x and abs(y) = y then sign = 'minus' res = 0 for i = 0

问题 In the following method, it doesn't do the addition for the SolarPanel correctly when the input window appears. When I type in "Electric" followed by "Yes/yes" i get the following Basic Price:20000 Electric Model:2000 Total:22000 but when I do "electric" + "yes/Yes" I get Basic Price:20000 Electric Model:2000 Solar Panel:5000 Total:27000 how come? public static int CalculateCost() { String typeOfCarCost = askCarType(); String SolarPanelCost = askSolarPanel(); int basicPrice = 20000; int

问题 I'm currently using a cronjob to cache a number into text from an API, I have two text files with numbers in them and I want to add both together like 16+4 and it prints at 20 I have no Idea how I would do this and would be really glad if someone could provide an example if It can be done. 回答1: Like this : <?php $file1 = '/path/to/file/file1.txt'; $file2 = '/path/to/file/file2.txt'; if(is_file($file1) && is_file($file2)) { $value1 = trim(file_get_contents($file1)); $value2 = trim(file_get
