swap

问题 i found this script to change images on hover. $(document).ready(function() { $('.rollover').hover(function() { swapImage(this); }, function() { swapImage(this); }); }); function swapImage(image) { var current = $(image).attr('src'); $(image).attr('src', $(image).attr('hover')); $(image).attr('hover', current); } But now i'm having the problem, that i want a smooth/soft transit and not that, what it does now. Here you can find a fiddle: JSfiddle Thanks and a nice sunday! 回答1: It is swapping

问题 In Hackerearth i tried solving bubble sort swap counting. and my output always different from correct output.for example; my output is 2475 and correct output is 2788 #include <iostream> using namespace std; int main() { int *A,tm,times=0; cin >> tm; A = new int[tm]; for(int i = 0; i<tm;i++) {cin >> A[i];} int temp; for(int i = 0; i<tm;i++){ for(int j = 0; j < tm-i-1;j++){ if(A[j] > A[j+1]){ times++;; temp = A[j]; A[j] = A[j+1]; A[j] = temp; } } } cout << times; return 0; } Am i doing

问题 I have been given an array and I'm asked to find out the number of Swaps required to sort the array using Bubble Sort Now we know that, we can find the comparisons by n(n-1)/2 but what I need is the number of actual swaps My first instinct was to use bubble sort and with each swap(), I incremented a Swap variable. But the time complexity of this is a very slow process and I'd like your help to find an optimized way to solve my dilemma P.S.: I also need to compare whether it is faster to sort

问题 I have a spreadsheet in Excel that contains a "Member ID" in the first column, with six variables, related to this Member ID, in the next six columns. I need to somehow convert these columns into rows, but still have the Member ID column at the beginning of each row. Here's the data as it stands (there are 5000 rows, hence hoping to find an automated solution): MEMBER 1 | AAA | BBB | CCC | DDD | EEE | FFF MEMBER 2 | BBB | ZZZ | FFF | AAA | RRR | SSS MEMBER 3 | YYY | FFF | OOO | MMM | PPP |

问题 I have declared and set a value in parameter @Data as ACCOUNT_NO|none|M=ACCOUNT_NO,ADD1|none|M=ADD1 I need to get a result as ACCOUNT_NO=ACCOUNT_NO|none|M,ADD1=ADD1|none|M . Which means I need to swap between the values before and after = Declare @Data varchar(100); Set @Data ='ACCOUNT_NO|none|M=ACCOUNT_NO,ADD1|none|M=ADD1' select @Data How to swap the values between before and after = using SQL Server? Expected Output if I execute the query ACCOUNT_NO=ACCOUNT_NO|none|M,ADD1=ADD1|none|M . Can

问题 public void sortDatabase(){ for(int j=0;j<productDatabase.size()-1;j++){ for(int i =0;i<productDatabase.size()-j-1;i++){ if(compareTo(i)){ Collections.swap(productDatabase,i,i++ ); //Με την Χρήση της Collections βιβλιοθήκης κάνω SWAP! Πρέπει να βάλω την βιβλιοθήκη όμως! } } } } public boolean compareTo(int index){ if(productDatabase.get(index).getPrice() > productDatabase.get(index++).getPrice()){ return true; } else return false; } Last time i posted my answer in a very bad way. Sorry for my

问题 How can we swap 2 arrays in constant complexity or O(1)? is there a way that we can do this? i have tried using pointers but it is giving error plus this wont help because it is just interchanging the pointers but not the arrays #include <algorithm> int AA[100], *A=AA, BB[100], *B=BB; swap(A, B); I have tried using vectors assignment operator as well but they have LINEAR complexity i.e O(N) not constant so is there any way we can swap two arrays in O(1)? (by using pointers or something else)

问题 I have many large multidimensional NP arrays (2D and 3D) used in an algorithm. There are numerous iterations in this, and during each iteration the arrays are recalculated by performing calculations and saving into temporary arrays of the same size. At the end of a single iteration the contents of the temporary arrays are copied into the actual data arrays. Example: global A, B # ndarrays A_temp = numpy.zeros(A.shape) B_temp = numpy.zeros(B.shape) for i in xrange(num_iters): # Calculate new

问题 I am having issues getting my sort to check every index. It skips the 3rd indices for j as in it goes i[0] , j[2] , to i[0] , j[4] I don't know why it is doing that?. Also, I am having trouble with my numbers actually be swapped. Does anybody know where my error is? static void selectionSort(int[] arr) { final long startTime = System.nanoTime(); // starts timer System.out.println("Selection Sort"); //************** Code For Sorting *****************// //***************************************

问题 How can I swap an image's SRC attribute, on click of that image? <a href="#"> <img src="./layout/images/search.png" /> </a> $('img[src="./layout/images/search.png"]').click(function () { $(this).attr('src',"./layout/images/search_select.png") }); 回答1: You can try this solution: $("img").click(function(){ $(this).attr("src","new.gif"); }) As David Hedlund points out this will change all images on a page due to the img selector. You could target an image using a class as sam152 suggests or, you
