## Problem statement 


In this challenge, you need to print the numbers **0-9** in a **sequential** manner, so that each number is printed after a random waiting time. For example, `i=0` might wait 4 seconds before being printed, whereas `i=1` might wait `2` seconds before being printed. You need to use the `sleep` function (given below) to achieve this. However, it will cause values to be printed in a non-sequential manner. Your task is to write the code in a way that the values are printed in a **sequential** manner.

>You need to implement the concept of `async`/`await` in this exercise.


## Input

`print` function

## Output

Displaying numbers from **0-9** sequentially

## Sample input
```
print()
```

## Sample output
