If the value of the expression,
mr Goodwill [35]

Answer:

<u>Arithmetic underflow</u>

Explanation:

Great question, it is always good to ask away and get rid of any doubts that you may be having.

Since the answer given is a negative. We can say the error that is seen here is an <u>Arithmetic underflow </u>error. This is because the answer given is a smaller absolute value which the computer cannot actually represent or save in its memory in the CPU. Therefore this is the closest representation of the arithmetic error displayed.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

Give a big-O estimate for the number additions used in this segment of an algorithm.
rjkz [21]
Big-O notation is a way to describe a function that represents the n amount of times a program/function needs to be executed. 

(I'm assuming that := is a typo and you mean just =, by the way) 

In your case, you have two loops, nested within each other, and both loop to n (inclusive, meaning, that you loop for when i or j is equal to n), and both loops iterate by 1 each loop.

This means that both loops will therefore execute an n amount of times. Now, if the loops were NOT nested, our big-O would be O(2n), because 2 loops would run an n amount of times.

HOWEVER, since the j-loop is nested within i-loop, the j-loop executes every time the i-loop <span>ITERATES. 
</span>
As previously mentioned, for every i-loop, there would be an n amount of executions. So if the i-loop is called an n amount of times by the j loop (which executes n times), the big-O notation would be O(n*n), or O(n^2). 

(tl;dr) In basic, it is O(n^2) because the loops are nested, meaning that the i-loop would be called n times, and for each iteration, it would call the j-loop n times, resulting in n*n runs.

A way to verify this is to write and test program the above. I sometimes find it easier to wrap my head around concepts after testing them myself.
