## [Average of Stream][task1]

> You are given a stream of numbers, `@N`.
>
> Write a script to print the average of the stream at every point.

### Example
~~~~
Input: @N = (10, 20, 30, 40, 50, 60, 70, 80, 90, ...)
Output:      10, 15, 20, 25, 30, 35, 40, 45, 50, ...
~~~~

* Average of first number is `10`.
* Average of first 2 numbers `(10+20)/2 = 15`.
* Average of first 3 numbers `(10+20+30)/3 = 20`.
* Average of first 4 numbers `(10+20+30+40)/4 = 25` and so on.
