c# - Fill a boolean array with List that contains indices that must be true -

-

मान लें कि मेरे पास सूची & lt; int & gt; NullValuesIds युक्त सूचकांक।

मैं NullValuesIds से हैं, और LINQ का उपयोग कर सूचकांक में true असाइन करने वाले एक बूलीयन सरणी को कैसे प्रारंभ कर सकता हूं? (बूलियन सरणी का आकार आकार 100 जैसा होता है)। 

  पूर्णांक maxIndex = nullValuesIds.Max (); // या कुछ अन्य अधिकतम var boolArray = संख्यात्मक। रेंज (0, मैक्स इंडैक्स)। चयन करें (NullValuesIds.Contains) .ओएरेरे ();

यदि प्रदर्शन महत्वपूर्ण है, तो यह बहुत तेजी से होगा यदि NullValuesIds एक हैशसेट और लेफ्टिनेंट; int & gt; ।

Edit: In the socket: The CanReceive () argument was the reason I was checking the input 1 millisecond While stepping into GDB, everything worked out. I have a problem with C sock send () / recv () do nothing if they are in non-debug mode. Even if std :: cout can not return their return value for some reason std :: cout is not working in my method I std: : Cerr can not even make a mistake It does not make sense to check that in GDB, because everything works perfectly as a virus in non-debug mode. C does not. //b - buffer // s - size // sd - socket descriptor int32_t TCP :: reception (char * b, uint32_t s) {error :: critical. SetErrorNumber (error: List :: noor); If (!

GO: Serve static pages -

-
I'm trying to display a static page with Go. Go: Package main import "net / http" function main () {fs: = http.FileServer (http.Dir ("static / house")) Http: .handle ("/", fs) http.ListenAndServe (": 4747", zero)} directory: project / stable home Html edit.html project.go When I run it, the web page displays links to edit.html and home.html instead of displaying a static page from home.html is. What am I doing wrong. Is this the best way to serve files? I know that there are other ways like From the HTML / templates package, but I'm not sure what is the difference between each of these methods and when. Thanks! fancy main () {http.Handle ("/", http.FileServer (Http) .ir ("static")) http.ListenAndServe (": 4747", zero)} You do not need static / home , just Static . and when you do not have index.html in / static , the directory instead Content appears. Just change the name of...

I want to use the front and rear camera at the same time in iOS development: when I take a photo back After the camera, the front camera can be opened and another can take a photo.
