Given `$N$`

numbers, read each one, calculate the running average and print it.

For example, given the three numbers `$4$`

, `$2$`

, and `$7$`

, print:

```
4
3
4.3333333333
```

The first number is the average of `$4$`

, the second number is the average of `$4$`

and `$2$`

, the third number is the average of `$4$`

, `$2$`

and `$7$`

.

The first line of the input will contain `$N$`

(`$0 < N < 100$`

).

The following line will contain `$N$`

integers, each between `$1$`

and `$1000$`

.

Print the running average (accurate to `$10^{-4}$`

) for each number, one per line.
