Mutable List

Create a mutable list and summarize its values.

MutableListExample.kt

fun main() {
    val added = 
    val scores = mutableListOf(3, 4, added)
    val total = scores[0] + scores[1] + scores[2]
    val count = scores.size

    println("total=$total")
    println("count=$count")
}

fun main() {
    val added = 
    val scores = mutableListOf(3, 4, added)
    val total = scores[0] + scores[1] + scores[2]
    val count = scores.size

    println("total=$total")
    println("count=$count")
}

fun main() {
    val added = 
    val scores = mutableListOf(3, 4, added)
    val total = scores[0] + scores[1] + scores[2]
    val count = scores.size

    println("total=$total")
    println("count=$count")
}

mutable A mutable list can be changed after it is created, and it is read like other lists.
