To add code to the merge sort algorithm to count the number of comparisons performed and at the end of the program that outputs "comparisons: " followed by the number of comparisons performed check the code given below.
What is sort algorithm?A sorting algorithm is a set of instructions that takes an input array, applies certain operations to the array (also known as a list), and outputs a sorted array.
Sorting algorithms are frequently covered early on in computer science courses because they offer a simple way to introduce other important concepts like Big-O notation, divide-and-conquer strategies, and data structures like binary trees and heaps.
When selecting a sorting algorithm, many factors need to be taken into account.

Managerial accounting information need not conform with U.S. GAAP. In fact, conformance with U.S. GAAP may be a deterrent to getting useful information for internal decision-making purposes. For example, when establishing an inventory cost for one or more units of product (each jersey or hat produced at Sportswear Company), U.S. GAAP requires that production overhead costs, such as factory rent and factory utility costs, be included. However, for internal decision-making purposes, it might make more sense to include nonproduction costs that are directly linked to the product, such as sales commissions or administrative costs.

Virtual memory layout [20] You have a 64-bit machine and you bought 8GB of physical memory. Pages are 256KB. For all calculations, you must show your work to receive full credit. (a) [1] How many virtual pages do you have per process? (b) [1] How many bits are needed for the Virtual Page Number (VPN)? (Hint: use part (a)) (c) [1] How many physical pages do you have? (d) [1] How many bits are needed for the Physical Page Number (PPN)? (Hint: use part (c)) (e) [1] How big in bytes does a page table entry (PTE) need to be to hold a single PPN plus a valid bit? (f) [1] How big would a flat page table be for a single process, assuming PTEs are the size computed in part (e)? (g) [10] Why does the answer above suggest that a "flat page table" isn't going to work for a 64-bit system like this? Research the concept of a multi-level page table, and briefly define it here. Why could such a data structure be much smaller than a flat page table? (h) [4] Does a TLB miss always lead to a page fault? Why or why not?
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

You want to know which files are large files (at least 0.1MB) in your data directory, but you do not want to go through them one by one. So you decide to design a regular expression to help with this. Locate the rule under the p1 target in your Makefile. This rule uses the Is command to list the contents of the data directory in your current folder. The -I option produces the long listing for these contents, which includes their size in bytes. The output of this is command is then piped as input into grep command. The-E option for the grep command allows searching through this text with a regular expression. Replace the regular expression in this grep command to search for any 6 digit number. Since the size of these files are displayed in bytes, the smallest possible six digit number: 100000 corresponds to 0.1MB. When this regular expression is correct, running "make p1" should display the three large files that can be found within the provided data directory. Tip: Start by composing a regex that matches any single digit, and test this to make sure that it works as expected. If you encounter trouble with one specific way of matching single digits, like \d, then please try to find another way that works with grep - E. Once this is working, look for a way to extend this pattern so that it must be repeated exactly six times to be matched.
You must pipe the command's output through grep in order to utilize grep as a filter. " | " is the symbol for pipe.
Explain about the grep?The full line containing the matched string is displayed by default when using grep. To display only the matched pattern, change this setting. Using the -o option, we may instruct grep to show only the matching string. Using grep -n, output should be displayed together with the line number: To display the file's line number where the matching line was found.
Within collections of files, the grep command can look for a string. It outputs the name of the file, a colon, the line that matches the pattern, and the pattern when it discovers a pattern that matches in more than one file.
Instead of putting a filename at the end of a grep command, use an asterisk to search all files in the current directory.

one drawback to the sequential search is that it cannot be used with an array that contains string elements. T/F
The sequential search has the limitation that it cannot be utilized with arrays containing string elements.Thus, it is false.
What sequential search, an array contains string elements?Searching linearly over an array of strings for the supplied string is an easy fix. Performing a modified binary search is a better solution.
Get the list of arrays. Get each element of the Array List object using the for-each loop. Make sure the array list's elements all contain the necessary string. Print the elements if applicable.
We compare the given string with the middle string, just like in a standard binary search. If the middle string is empty, we linearly search on both sides for the nearest non-empty string x.
Therefore, it is false that one drawback to the sequential search is that it cannot be used with an array that contains string elements.

Which of the following activities is least likely to result in a segmentation fault?
Question 19 options:
Removing an element from the middle of a linked list without fixing the pointers afterwards
Growing the stack too large, such as with an unbounded recursive function
Trying to write into protected space, such as modifying the code segment of the program
Accessing a memory address outside its boundaries
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.

design a 32 bit counter that adds 4 at each clock edge the counter has reset and clock inputs upon reset the counter output is all 0
The counter is a digital sequencer, here a 4-bit counter. This simply means that you can count from 0 to 15 or vice versa depending on the counting direction (up/down).
The counter value (“count”) is evaluated on each positive (rising) edge of the clock cycle (“clk”).
If the "reset" input is logic high, the counter is set to zero.
If the "load" signal is logic high, the counter is loaded with the "data" input. Otherwise, count up or count down. If the "up_down" signal is logic high, the counter counts up, otherwise it counts down.
What are counters and their types
A counter is a sequential circuit. A well-known counter is a digital circuit used for counting pulses. Counters are the widest use of flip-flops. There are two types of counters. Asynchronous or ripple counter.
What are counters used for?

{ $$ = createLiteral(scanned_text); }
The blocks that would most likely be used to create a string constant from scanned code is { append_scan(yytext); return TOKEN_STRING; }. The correct option is c.
What is scanned code?Code scanning makes it possible to find vulnerabilities and fix them before they are released into production, removing the cybersecurity risks they present.
When scanning a string, the literal "EOL" means "end of the line." When Python encounters an EOL error, it means that it has reached the end of a line in a string. You might have done this by forgetting the closing quotes or by trying to make a string span more than one line. Single or double quotes around strings.
Therefore, the correct option is c, { append_scan(yytext); return TOKEN_STRING; }.
