Is the book referring to binary and how the computer open a file from an external device etc? and what are the elements is it talking about?

Just use the example to base your answers on.

For example, problem 1:

Step 1. Understand the problem: A list of x many values will be entered and you have to display the total along with how many there are (x).

Step 2. Devise a solution - draw a similar diagram as seen in the book:

Initialise values -> total=0, count=total
Process numbers -> process element in list while current element is not equal to 0 -> read value, add to total, add to count
Display answers -> print total, print count

Initialise vals:

count = 0
total = 0
​

Process numbers:

while not value of element in list = 0, do:

read element;
add element to total val;
add 1 to count
​

end while
​

Display answer:

Print: total (gives total cost)
Print: count (gives number of items)​
