Set the target value be an integer with a value of 3.
Call the linearSearch method with the Map and target value as parameters.
Store the result of the search as a boolean variable called result.
If the result is true, the message "Target found in the Map." should be printed to the console.
If the result is false, the message "Target not found in the Map." should be printed to the console.
