We need a function that will take the first element of the left vector and the last element of the right vector and return a message with the sum Sum is $sum. If at least one vector is empty, it should return None. Use the features of Option to prevent runtime errors.

Sample Input 1: 

1 4 3 8
3 5 1 8

Sample Output 1: 

Some(Sum is 9)
