The goal of this challenge is to design a cash register program. You will be given two decimal numbers. The first is the purchase price (PP) of the item. The second is the cash
(CH)
given by the customer. Your register currently has the following bills/coins within it: 'PENNY': 01, 'NICKEL': .05, 'DIME': .10, 'QUARTER': .25, 'HALF DOLLAR': .50, 'ONE': 1.00, 'TWO': 2.00, 'FIVE': 5.00, 'TEN': 10.00, 'TWENTY': 20.00, 'FIFTY': 50.00, 'ONE HUNDRED':
100.00
The aim of the program is to calculate the change that has to be returned to the customer. Each input string contains two numbers which are separated by a semicolon. The first is the Purchase price (PP) and the second is the cash(CH) given by the customer. For each line of input return single line string is the change to be returned to the customer. In case the
CH
, return "ERROR". If
CH==PP
, return "ZERO". For all other cases return a comma separated string with the amount that needs to be returned, in terms of the currency values provided. The output should be alphabetically sorted. # # Complete the 'MakeChange' function below. # # The function is expected to return a STRING. # The function accepts STRING purchaseInfo as parameter. # def MakeChange(purchaseInfo): # Write your code here n if

if (cash < price):
return "ERROR"
if (cash == price):
return "ZERO"
cashBack = cash - price;
change =[]
while (cashBack > 0.01):
if (cashBack >= 100.0):
change.append("ONE HUNDRED")
cashBack -= 100.0
elif (cashBack >= 50.0):

From the following activities, the one that is least likely to result in a segmentation fault is: "Removing an element from the middle of a linked list without fixing the pointers afterwards" (Option A)
What is a segmentation fault?A segmentation fault or accessibility violation is a fault, or failure condition, reported by memory-protected hardware that alerts an operating system that software has attempted to access a restricted portion of memory. This is a type of generic protection fault on ordinary x86 machines.
Check whether your compiler or library can be made to check limits on I at least in debug mode, to remedy a segmentation error. Buffer overruns that write trash over excellent pointers can trigger segmentation faults. These actions will significantly minimize the chance of segmentation faults and other memory issues.

However, this will depend on whether your car's display screen is compatible with your phone and whether the navigation app you are using is compatible with your car's display screen.
For example, some newer models of cars have built-in Android Auto functionality, which allows you to use your car's display screen to access certain apps and features on your Android phone. If your car has this capability and you are using an Android Auto-compatible navigation app, you may be able to view maps and navigation information on your car's display screen.
Similarly, if you are using a navigation app that is compatible with Ap*ple CarPlay (such as Go*ogle Maps or Waze), you may be able to view maps and navigation information on your car's display screen if your car has Apple CarPlay functionality.
It is also worth noting that some cars have their own built-in navigation systems that can be used independently of your phone. In this case, you may not need to use your phone's navigation app at all.

We have 2^48 pages per person. The number of physical pages is 2^16.. 48 bits of VPN are mapped to 16 bits of PPN. The PTE size is 2B. The page table size is 2^49 B.
What are the steps to calculate pages per person, physical pages, VPN ,PTE size and the table size?We know that;
Virtual Address = 64bits
Virtual Address Space = 2^Virtual Address = 2^64B
Physical Address Space = 4GB = 4 X 2^30 B = 2^32 B
Physical Address = log_2(Physical Address Space ) = log_2(2^32)
= 32 * log_2(2) = 32 bits.
Page size = 64KB =2^16 B
a) No of Virtual Pages = Virutal Address Space/PageSize
= 2^64B / 2^16 B = 2^48
b) NoOfPhysicalPages = PhysicalAddressSpace/PageSize
= 2^32 B / 2^16 B = 2^16
c) VPN (in Bits) = log_2(NoOfVirtual Pages) = log_2(2^48) = 48
PPN(inBits)=log_2(NoOfPhysicalPages)= log_2(2^16) = 16
Thus 48 bits of VPN are mapped to 16 bits of PPN.
d) PTE( Page Table Entry) holds the Physical Page Number of given Virtual Page along with many information about the page.
PTEsize = PPN(inBits) = 16 bits = 2B
e) Flat page table is single level page table. A page table contains the Physical Page number for a given page number. It helps in the translation of Vitual Address to Physical Address.
PageTableSize = NoOfVirtualPages*PTEsize = 2^{48}*2B = 2^49

Ruudy is analyzing a piece of malware discovered in a pentest. He has taken a snapshot of the test system and will run the malware. He will take a snapshot afterwards and monitor different components such as ports, processes, event logs, and more for any changes. Which of the following processes is he using?
Answers
Ruudy is using the process called Host integrity monitoring.
What is Host integrity ?Host Integrity makes ensuring that client PCs are secure and adhere to the security guidelines established by your business. Enterprise networks and data are secured using Host Integrity policies to specify, enforce, and restore client security. In order to make sure that client PCs are secure and adhere to a company's security standards, Host Integrity (HI), a function of Symantec Endpoint Protection (SEP), can be employed. Host Integrity policies can be used to specify, enforce, and correct client security as specified by the policy. A Microsoft patch or set of patches, for instance, may be checked to see if they are installed on a client using an HI policy. Clients can be isolated from particular network access if they don't match the requirements until they do.To learn more about network, refer:

Consider the following incomplete code segment, which is intended to print the sum of the digits in num. For example, when num is 12345, the code segment should print 15, which represents the sum 1 + 2 + 3 + 4 + 5. int num = 12345;int sum = 0;/ missing loop header /{sum += num % 10;num /= 10;}System.out.println(sum);Which of the following should replace / missing loop header / so that the code segment will work as intended?
Answers
The term that should replace / missing loop header / so that the code segment will work as intended is option A: while (num > 0).
What is the header about?The body of the code is executed once for each iteration, and the header specifies the iteration.
The body of a for loop, which is executed once each iteration, and the header, which specifies the iteration, are both components. A loop counter or loop variable is frequently declared explicitly in the header.
Therefore, the module and division action inside the loop must be our main attention in order to comprehend why. The crucial thing to remember is that we are adding the numbers in reverse order and that we must repeat this process until we reach the initial number (1%10 = 1). As a result, num must equal one in order to compute the final operation.
