Explanation:
The when expression in Kotlin is similar to the switch statement in other languages, allowing you to evaluate multiple possible values of a variable and execute different code based on the value. In this code, the x variable is evaluated against the cases of 1 and 2. Since x is neither 1 nor 2, the default case is executed, which prints the message "x is not 1 or 2" to the console.
