Objective
Write a Java program called SumAndAverage to prompt a user to enter a whole
number (called n) between 1 and 100 inclusive. Compute the sum of the sequence
from 1 to n and display the result. Also compute the average of the sequence from 1
to n and display the result. If a user enters a number less than 1 or greater than 100,
inform the user the number is invalid.
You are expected to use a FOR loop to compute the sum from 1 to n.
