Android Studio – Seperate integers from 1 variable into different variables

Not sure how to explain this the best but I have a variable with 4 int’s in it. Is there a simple way to extract the 4 int’s into 4 seperate var’s?

Example:
The variable contains: 4567

And then the output is:

   var1 = 4 
   var2 = 5
   var3 = 6
   var4 = 7

    You can do this:

    val input = 4567

val var1 = input / 1000
val var2 = (input % 1000) / 100
val var3 = (input % 100) / 10
val var4 = (input % 10)

    Another way can be:

    val n = 4567
val (var1, var2, var3, var4) = "$n".map { it.digitToInt() }

    Note that this will fail if number contains less than 4 digits.
