Hi UiPath community!

I would really appreciate some help with the following issue:

I have a number (Eg: 151), and I have to check two things:

- Is it a three digit number?
- Does it start with “1”?

If yes to both those conditions, I have to **replace the first “1” with “0”**. Thus, “151” should be changed to “051”. Unfortunately, *I cannot simply subtract 100 from the number as the result will be “51”*. Are there any other ways to do this? Can anyone help me with this?

Thanks!
