Answer 1

The listOf() is immutable, means you can't change the value.

Eg - var k = listOf(5,6,4)
k[0] = 9

It will give me error because it's immutable you can't edit it.

And mutanleList() ,means you can edit it.

For eg - var k = mutableListOf(5,6,5)
k[0] = 2

Now k's 0th elements is 2

It's similar to python's list and tuple

Mutable eg -
