Assume that a finite number of resources of a single resource type must be managed. Processes may ask for a number of these reso

urces and —once finished—will return them. As an example, many commercial software packages provide a given number of licenses, indicating the number of applications that may run concurrently. When the applicationis started, the license count is decremented. When the application is terminated, the license count is incremented. If all licenses are in use, requests to start the application are denied. Such requests will only be granted when an existing license holder terminates the application and a license is returned.The following program segment is used to manage a finite number of instances of an available resource. The maximum number of resources and the number of available resources are declared as follows:#define MAX RESOURCES 5int available resources = MAX RESOURCES;When a process wishes to obtain a number of resources, it invokes the decrease_count() function:/* decrease available resources by count resources *//* return 0 if sufficient resources available, *//* otherwise return -1 */int decrease_count(int count) {if (available resources < count)return -1;else {available resources -= count;return 0;}}When a process wants to return a number of resources, it calls the increase_count() function:/* increase available resources by count */int increase_count(int count) {available resources += count;return 0;}The preceding program segment produces a race condition. Do the following:Identify the location and variables involved in the race condition and use a semaphore to fix the race condition.

devlian [24]

Answer:

Answer:

the logo of the company or corporation

Explanation:

Usually, the symbol that determines who owns the intellectual property is the logo of the company or corporation. The logo of a website is technically the logo of the brand which has the rights to all of the information represented on the site and ultimately the intellectual property of the site itself. Since there are various board members that usually make up the company that owns the intellectual property, the logo is a way of representing all of these members as a single entity.

A proper divisor of a positive integer $n$ is a positive integer $d &lt; n$ such that $d$ divides $n$ evenly, or alternatively i
juin [17]

Answer:

The program written in Python is as follows:

<em>See Explanation section for line by line explanation</em>

for n in range(100,1000):

     isum = 0

     for d in range(1,n):

           if n%d == 0:

                 isum += d

     if isum == n * 2:

           print(n)

Explanation:

The program only considers 3 digit numbers. hence the range of n is from 100 to 999

for n in range(100,1000):

This line initializes sum to 0

     isum = 0

This line is an iteration that stands as the divisor

     for d in range(1,n):

This line checks if a number, d can evenly divide n

           if n%d == 0:

If yes, the sum is updated

                 isum += d

This line checks if the current number n is a double-perfect number

     if isum == n * 2:

If yes, n is printed

           print(n)

<em>When the program is run, the displayed output is 120 and 672</em>
