Mutable Map

The output of two maps

Report a typo

What will be the console output of the following function?

fun main() {
    val map1 = mutableMapOf<String, Int>()
    val map2 = mapOf<String, Int>()
    map1["Apple"] = 300
    map1["Banana"] = 400
    map1["Lemon"] = 250
    map2["Melon"] = 400
    map2["Mango"] = 600
    map1.putAll(map2)
    println(map1)
}

Select one option from the list

{Apple=300, Banana=400, Lemon=250, Melon=400, Mango=600}

{Melon=400, Mango=600}

Compile-time error

{Apple=300, Banana=400, Lemon=250}
