var & val (#3)

Define two vars: x and y. Swap their contents. First try x = y, y = x, then fix the erroneous solution:

var x = 1
var y = 2
// Perform swap here
println(x) // 2
println(y) // 1

Your code should remain unchanged for different initializers, like var x = "first", var y = "second". Thus, using x = 2, y = 1 is not the expected solution.

You may need to introduce a third auxiliary val.
