Answer:

cause

According to my research, I can say that based on the information provided within the question this is an example of a "cause". This refers to something that makes something else happen, and is usually stated by the word "because". For example in this situation the a "planned increase in the use of the computer by operating departments" caused a "Competition for computer time during periods of high demand to become intense".

Under which of the following conditions will evaluating this boolean expression
zzz [600]
1.) 
<span>((i <= n) && (a[i] == 0)) || (((i >= n) && (a[i-1] == 0))) </span>

<span>The expression will be true IF the first part is true, or if the first part is false and the second part is true. This is because || uses "short circuit" evaluation. If the first term is true, then the second term is *never even evaluated*. </span>

<span>For || the expression is true if *either* part is true, and for && the expression is true only if *both* parts are true. </span>

<span>a.) (i <= n) || (i >= n) </span>

<span>This means that either, or both, of these terms is true. This isn't sufficient to make the original term true. </span>

<span>b.) (a[i] == 0) && (a[i-1] == 0) </span>

<span>This means that both of these terms are true. We substitute. </span>

<span>((i <= n) && true) || (((i >= n) && true)) </span>

<span>Remember that && is true only if both parts are true. So if you have x && true, then the truth depends entirely on x. Thus x && true is the same as just x. The above predicate reduces to: </span>

<span>(i <= n) || (i >= n) </span>

<span>This is clearly always true. </span>

The factorial of n is equal to ______.
alexdok [17]

Answer:

n! = n*(n-1)*(n-2)*(n-3)* ... *2*1

Explanation:

The factorial operator is simply a mathematical expression of the product of a stated integer and all integers below that number down to 1.  Consider these following examples:

4! = 4 * 3 * 2 * 1

4! = 12 * 2 * 1

4! = 24

6! = 6 * 5 * 4 * 3 * 2 * 1

6! = 30 * 4 * 3 * 2 * 1

6! = 120 * 3 * 2 * 1

6! = 360 * 2 * 1

6! = 720

So, the factorial of n would follow the same as such:

n! = n * (n-1) * (n-2) * ... * 2 * 1

Cheers.
