operations

问题 I've written a piece of java code that when given an array (arrayX), works out the prefix averages of that array and outputs them in another array (arrayA). I am supposed to count the primitive operations and calculate the Big-O notation (which i'm guessing is the overall number of calculations). I have included the java code and what I believe to be the number of primitive operations next to each line, but I am unsure whether I have counted them correctly. Thanks in advance and sorry for my

问题 I have a counter working that counts every frame. what I want to do is divide this by time to determine the FPS of my program. But I'm not sure how to perform operations on timing functions within python. I've tried initializing time as fps_time = time.time fps_time = float(time.time) fps_time = np.float(time.time) fps_time = time() Then for calculating the fps, FPS = (counter / fps_time) FPS = float(counter / fps_time) FPS = float(counter (fps_time)) But errors I'm getting are object is not

问题 I have a requirement to test some load issues with regards to file size. I have a windows application written in C# which will automatically generate the files. I know the size of each file, ex. 100KB, and how many files to generate. What I need help with is how to generate a string less than or equal to the required file size. pseudo code: long fileSizeInKB = (1024 * 100); //100KB int numberOfFiles = 5; for(var i = 0; i < numberOfFiles - 1; i++) { var dataSize = fileSizeInKB; var buffer =

问题 I am stuck on a problem I have for a homework assignment that is asking me to ask the user fora digit ranging from 1 digit to 5 digits (eg. they can input 1, 12, 123, 1234) I know how to ask the user for whatever number they want, using a loop and then using the mov ah, 1h function, but I want to take the user's input, let's say 123, and then store that number in a variable that I've created, Y. Then I want to process it, I already know how to process the number, but only when I've already

问题 I'm new to PHP in general. I was messing with this code until I wanted to execute the function in one set instead of having to set and add, sub, div, mult function. How do I go about setting the variable operator with the two num sets? Example pseudo code: <?php $Num1 = 10; $Num2 = 5; $operation = /; $Sum = $Num1 $operation $Num2; return $Sum; Or something like: <?php // creating Class "Math" class math { //Executing the function function exec($info = array()) { return $info['num1'] $info[

问题 This question already has answers here : Closed 11 years ago . This is probably pretty basic... but I don't seem to get it: How does (2 & 1) = 0 (3 & 1) = 1 (4 & 1) = 0 etc.. This pattern above seems to help find even numbers or (0 | 1) = 1 (1 | 1) = 1 (2 | 1) = 3 (3 | 1) = 4 (4 | 1) = 5 (5 | 1) = 5 I know how boolean algebra works between bits. But I don't understand how Boolean algebra works with integers (in C# at the least). thanks in advance. 回答1: It works the same way in C# as it does

问题 We are using Hudson for our Continuous Integration server and it's great. We have 2 issues with it, which are mildly related. https://hudson.dev.java.net/issues/show_bug.cgi?id=2736 The build order in Hudson means that the downstream dependencies get built a lot more than they need to be. Hopefully this issue will be addressed soon. Since these things are getting built so frequently, the build history is massive. We really don't need 1000 build items in the history for some of the jobs. My

问题 I'm trying to check whether or not a number has the second bit flag (ie 0000 0010). My code is as follows: int flags = Integer.parseInt(fields[1]); String strflags = Integer.toBinaryString(flags); flags = Integer.parseInt(strflags); int secondBitTest = Integer.parseInt("00000010", 2); if((flags & secondBitTest) == 2) { System.out.println("YES"); } However I think I might be doing this wrong, since when I try to input 147 nothing is returned. 回答1: You can check if any bit is set using this
