  परीक्षण ("अंकगणित") {जोर देना (गणना: अरिथमेटिक (5, 10) === 30)}

मुख्य 

  डीईएफ अंकगणित (ए: इंट , बी: इंट): इंट = {val सी = बी - एक वैल तीसरा = बी + सी वेल चौथा = तीसरा सी वैल पांचवीं चौथी = सी पांचवीं सी}   <पी> स्काला में एक  val fibs = fibFrom (1, 1) .take (7)  का उपयोग कर बना सकता है। क्या यह एक धारा का उपयोग करना संभव है जो स्काला में  अंकगणित  दृश्य बनाता है? यदि सकारात्मक है, तो इसे कैसे कार्यान्वित करें?

एक फाइबोनैचि अनुक्रम एक अंकगणितीय अनुक्रम है और आप जो भी क्रम बना सकते हैं आप चाहते हैं: 

  scala & gt; Val s: स्ट्रीम [Int] = 0 # :: s.map (_ + 5) s: स्ट्रीम [Int] = स्ट्रीम (0,?) स्केल & gt; S (10) res0: Int = 50 स्केल & gt; (एस ले लो 10) .toList res1: सूची [इंट] = सूची (0, 5, 10, 15, 20, 25, 30, 35, 40, 45)

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.
