Android Kotlin for Java Developers Modelling Solitaire Finishing the Pieces

Shouldn't the answer be 012? Aren't 0 and 2 inclusive in the range?

Also the answer in the question 3 contradicts with the answer in the first question

for (var i in 0..2) { 

Will not produce "0 1 2" because it will actually produce an error. This error to be precise:

'var' on loop parameter is not allowed

I have not completed the "Kotlin for Java Developers" course yet, so I don't know if it is brought up in the course. But neither var nor val is supported when declaring an index variable for a for loop.

The third quiz code:

for (i in 23..25) { 

Correctly omits the var keyword and therefore will produce "23 24 25" since it is an inclusive range as you correctly noted.

Thank you for confirming that up. I too noticed that difference but was not sure if that's not allowed in the for loop.
