Swap

Report a typo

Suppose you have two variables a and b that store some numbers. Swap the values of these variables. For example, if a = 3 and b = 5, then after executing the code, a will contain 5, and b will contain 3.

Try to do it with the help of the third variable c. You can imagine that variables are just boxes with values, and you need to swap their contents, like this:

Example of replacing values of two variables with a third variable.

fun main() {

// Don't be afraid of the code below!

// In the future, you will definitely cope with it, but for now just ignore it.

var (a, b) = readLine()!!.split(" ").map { it.toInt() }

// Write only exchange actions here. Do not touch the lines above

val c =

// Do not touch the lines below

print("$a $b")

}
