Write a snippet of code—not a function—that:

• declares a variable digit and initializes it to the character 'B'
• declares a variable named airTemperature and initializes it to 78.8
• declares a variable score and initializes it to 99
• declares a variable named semesterHasStarted and initializes it to true

Note that because Kotlin performs type inference, you can and should solve this problem without explicitly specifying any types.
