A Fibonacci sequence is composed of elements created by adding the two previous elements. The

simplest Fibonacci sequence starts with $1,1$ and proceeds as follows:

$1,1,2,3,5,8,13,...$

However, a Fibonacci sequence can be created with any two starting numbers.

a$.$ Prompt the user to enter the first two numbers in a Fibonacci sequence and the total number of

elements requested for the sequence. Find the sequence and store it in an array by using a while

loop.

b$.$ Perform three testing scenarios in the command window.
