Why val array makes no error while I assign something in some array position?

I declared an array and assign 3 elements using val keyword. So I thought I cannot change any element in the array. But I could! Why it works? But when I assign a new array as a whole, then I got compiler error saying something like this - val cannot be assigned again. Why does this happen? Please see my code below to understand: https://code.sololearn.com/cNn9QTwPx8hN/?ref=app Sorry for my bad English.

Have a look at following stackoverflow question, https://www.google.com/url?sa=t&source=web&rct=j&url=https://stackoverflow.com/questions/50466863/kotlin-val-cannot-be-reassigned-but-can-be-reassigned-by-accessing-from-inde&ved=2ahUKEwiM2J2Bx7DyAhXHZSsKHQXnANAQFnoECCEQAQ&usg=AOvVaw12su001bDZJ-s6mKXx5kM3 From what i understand, you can't change the reference to new object when using val but you can change the reference of the object inside that object (referring to int objects inside array). I might be wrong .
