Answer:
Check the explanation
Explanation:
We can utilize the above algorithm with a little in modification. If in each of the iteration, we discover a node with no inward edges, then we we’re expected succeed in creating a topological ordering.
If in a number of iteration, it becomes apparent that each of the node has a minimum of one inward edge, then there must be a presence of cycle in the graph.
So our algorithm in finding the cycle is this: continually follow an edge into the node we’re presently at (which is by choosing the first one on the adjacency list of inward edges to decrease the running time).
Since the entire node has an inward edge, we can do this continually or constantly until we revisit a node v for the first time.
The set of nodes that we will come across among these two successive visits is a cycle (which is traversed in the reverse direction).

Explanation:
Assuming you have Windows 8 or 10 as the operating system, you would need to do the following. In the search input in the taskbar search for "Create a System Restore Point". In this window, navigate to the System Protection tab. Here, you need to click on the drive you want, we can do C first, and click on the button that says "configure". Here you want to turn on System Protection and set the disk space to 5%. Now click apply and ok and repeat for drive D.
Once that is done you will need to create a manual restore point by clicking the button that says create and giving it the name of your choice.

Answer:
C 1,2,3,4
Explanation:
This means I want to count from 0-4 and set it o the current loop I am currently on.
for i in range(0, 5):
print("i currently equals: ", i)
The result will be
i currently equals: 0
i currently equals: 1
i currently equals: 2
i currently equals: 3
i currently equals: 4
Answer:
BlueBorne Attack
Explanation:
If you're using a Bluetooth enabled device, whether it's a smartphone, laptop, smart TV, or any other IoT device, you risk malware attacks that can be remotely performed to take over your device, even without requiring any interaction from your side.
Security researchers have just discovered a total of 8 zero-day Bluetooth protocol vulnerabilities affecting more than 5.3 billion devices - from Android, iOS, Windows and Linux to the Internet of devices (IoT) - using technology short-range wireless communication
Using these vulnerabilities, security researchers at IoT security firm Armis created an attack, called BlueBorne, which could allow attackers to completely take over Bluetooth-enabled devices, spread malware, or even establish a “man” connection. -in-the-middle ”to gain access to device critical data and networks without requiring any victim interaction.
