+// EXERCISE
+// Average calculator has a flaw.
+// It divides the numbers by the length of the array.
+// This results in wrong calculatio.
+//
+// For example:
+//
+// When you run it like this:
+//   go run main.go 1 5
+// It tells you that the average number is:
+//  1.2
+// Whereas, actually, it should be 3.
+//
+// Fix this error.
+// So that, it will output 3 instead of 1.2
+//
+// Do not change the length of the array.
