 Your server should be listening on `0.0.0.0:8080`.

+A Go HTTP server is also provided for comparison. It uses the standard "net/http" package. To run it:
+
+```shell
+go run golang/server.go
+```
+

golang/server.go

+package main
+
+import (
+  "fmt"
+  "net/http"
+  //"runtime"

+
+func handle_root(w http.ResponseWriter, r *http.Request) {

+  a, b = 0, 1

+  for i = 0; i < n; i++ {
+    a, b = b, a + b
+  }
+
+  return a
+}
+
+func handle_fibonacci(w http.ResponseWriter, r *http.Request) {
