position

问题 Can anyone help me with finding an algorithm to change a position of a node in a linked list according to the input? Example: I have the linked list: 1->2->3->4->END and the user chose the second node and the index 4. The algorithm will give us the result: 1->3->4->2->END. Thanks for your help! 回答1: It is really easy to move nodes in a linked list because they are done for that... To change a node's position, just change it's next pointer to the next node address, and the previous node's next

See the comments towards the end of this procedure. procedure ScreenShot(var Bitmap: TBitmap; const MonitorNum: Integer; const DrawCursor: Boolean; const Quality: TPixelFormat); var DC

问题 I wish to collect the pixel location (row-i, col-i) by right-clicking the mouse when the image is displayed. This is a simple example about a picture downloaded from the internet: import urllib import cv2 from win32api import GetSystemMetrics path_image = urllib.urlretrieve("http://www.bellazon.com/main/uploads/monthly_06_2013/post-37737-0-06086500-1371727837.jpg", "local-filename.jpg")[0] img = cv2.imread(path_image,0) width = GetSystemMetrics(0) height = GetSystemMetrics(1) scale_width =

问题 I rendered a scene having earth and a satellite. The position of the satellite is collected and updated by a thread. The position data is provided by an background calculation program. // main.cpp void CollectCraft(void) { SetupChannel(); int iFlag = 1; while(iFlag > 0) { iFlag = CollectData(); Sleep(10); } CloseChannel(); } int main(void) { CreateThread(NULL, NULL, (LPTHREAD_START_ROUTINE)CollectCraft, 0, NULL, NULL); // in collect.cpp RenderMainWindow(); // in render.cpp return 1; } The

问题 I have a map image (1080x1080px) I want this to be the the background of the body or a container div. I need the image to stay fixed in its place always, even when resizing the browser window.
