Multi-dimensional list

Look at the 3D list of mutList3D:

val mutList3D = mutableListOf(
    mutableListOf(mutableListOf(0, 1), mutableListOf(2)),
    mutableListOf(mutableListOf(4, 5, 6, 7), mutableListOf(8, 9)),
    mutableListOf(mutableListOf(10, 11), mutableListOf(12)),
    mutableListOf(mutableListOf(13, 14, 15), mutableListOf(16, 17, 18))
)

Match the println() commands and their output:

Match the items from left and right columns

println(mutList3D.size)

println(mutList3D.first().size)

println(mutList3D[mutList3D.size - 1].last())

println(mutList3D.first().last().size)

[16, 17, 18]
