Formatting multiple array values in a single expression

Hello,

I want to create an expression where multiple array values can be changes in a single expression.

For eg.
Input - [1,4,20,22,30].
In this I just want to change the values which are less than 10 and put a ‘0’ before those filtered value.
Output - [01,04,20,22,30]

Can anyone suggest what will be the best possible way to achieve this?

Thanks in Advance
