swap

问题 We are testing under Sun Studio 12.3. We are catching a compiler error that's not present under 12.4 and later. Its not present under 12.1 and earlier, but that's because the compiler has trouble with AES instructions. Its also not present under other compilers, like Clang, GCC, ICPC and VC++. The error is: /opt/solarisstudio12.3/bin/CC -DDEBUG -g3 -xO0 -D__SSE2__ -D__SSE3__ -D__SSSE3__ \ -D__SSE4_1__ -D__SSE4_2__ -D__AES__ -D__PCLMUL__ -D__RDRND__ -D__RDSEED__ -D__AVX__ \ -D__AVX2__ -D__BMI_

问题 What i would like to do is to show the products other versions of images on mousemove from left to right. Here's the simple html example: <article> <figure data-imageList="image2.jpg,image3.jpg,image4.jpg"> <img data-src="main-image.jpg" src="main-image.jpg"> </figure> </article> As you can see at html, the images src will be change from the data-imageList. When user mouseout from the article, the main-image.jpg will appear again. This will the default image. The function should be trigger

问题 I am using PHP/MYSQL. I want in my frontend, for the users to sort and rearrange database records entered by the user himself in an earlier stage. The records uploaded by the user may sometimes inserted into the database randomly, so in the user profile he/she might have a facility to rearrange the the rows in the database according to there wise. Can any one provide me a script that would help me to do so. id title date desc 1 s1 s1_date s1_desc 2 s2 s2_date s2_desc 3 s3 s3_date s3_desc 4 s4

问题 So I am basically trying to make a SWAP(t,x,y) macro that exchanges two arguments of type t. I am trying to think of going around the problem when these two arguments are of the form v[i++] and w[f(x)] , i.e. SWAP(int, v[i++], w[f(x)]). The code below is basically crashing ... #define SWAP(T,x,y) {T *p = x; T *q = y; T z = *p; *p = *q; *q = z;} int f (int x){ return (0-x); } int main(void) { int v[] = {1,2,3}; int i = 0; int w[] = {4,5,6}; int x = -1; int *p = v; int *q = w; SWAP(int*, v[i++]

问题 How do you do a "drag and swap" in c#? I want my first label to replace the second, and vice versa. Thanks! Below is my drag and drop code--I'm hoping I can insert something under the dragdrop method but I don't know how to reference where the data is being posted. private void DragDrop_MouseDown(object sender, MouseEventArgs e) { Label myTxt = (Label)sender; myTxt.DoDragDrop(myTxt.Text, DragDropEffects.Copy); } private void DragDrop_DragEnter(object sender, DragEventArgs e) { if (e.Data

问题 Can I swap the keys of two values of a Hashmap, or do I need to do something clever? Something that would look something like this: Map.Entry<Integer, String> prev = null; for (Map.Entry<Integer, String> entry: collection.entrySet()) { if (prev != null) { if (entry.isBefore(prev)) { entry.swapWith(prev) } } prev = entry; } 回答1: Well, if you're just after a Map where the keys are ordered, use a SortedMap instead. SortedMap<Integer, String> map = new TreeMap<Integer, String>(); You can rely on

问题 I'm implementing the copy-and-swap idiom for operator= of a small non-owning-memory-referencing object I've designed. When MemRef is referencing a piece of a buffer whose lifetime I trust, _ptr points into the buffer, as you'd expect. What is unusual about this MemRef is that it consists not only of a _ptr and a _len , but also a _memory std::string : there are certain users (or situations) of this class whom I do not trust to protect their memory; for them, I actually copy their memory into

问题 I am trying to create a function that will swap a specific number in a matrix with a specific number in the same matrix. For examlpe, if I start with A = [1 2 3;1 3 2], I want to be able to create B = [2 1 3; 2 3 1], simply by telling matlab to swap the 1's with the 2's. Any advice would be appreciated. Thanks! 回答1: If you have the following matrix: A = [1 2 3; 1 3 2]; and you want all the ones to become twos and the twos to become ones, the following would be the simplest way to do it: B = A
