6-Write a BNF description of the precedence and associativity rules defined for the expressions in Problem 9 - chapter 7 of the textbook . Assume the only operands are the names a,b,c,d, and e.
Answers
The BNF description, or BNF Grammar, of the precedence and associativity rules are
\(<identifier>\text{ }::=a|b|c|d|e\)
\(<operand>\text{ }::=\text{ }NUMBER\text{ }|\text{ }<Identifier>\)
\(<factor>\text{ }::=\text{ }<operand>|\text{ }-<operand>|\text{ }(<expression>)\)
\(<power>\text{ }:=\text{ }<factor>\text{ }|\text{ }<factor>\text{**} <power>\)
\(<term>\text{ }::=\text{ }<power>\text{ }\\|\text{ }<term>*<power>\text{ }\\|\text{ }<term>/<power>\\\\<expression>\text{ }::=\text{ }<term>\text{ }\\|\text{ }<expression>+<term>\text{ }\\|\text{ }<expression>-<term>\)
BNF, or Backus-Naur Form, is a notation for expressing the syntax of languages. It is made up of a set of derivation rules. For each rule, the Left-Hand-Side specifies a nonterminal symbol, while the Right-Hand-side consists of a sequence of either terminal, or nonterminal symbols.
To define precedence in BNF, note that the rules have to be defined so that:
A negation or bracket matches first, as seen in the nonterminal rule for factorA power matches next, as seen in the rule defining a factorA multiplication, or division expression matches next, as seen in the rule defining a termFinally, addition, or subtraction match, as seen in the rule defining an expression.To make sure that the expression is properly grouped, or associativity is taken into account,
Since powers associate to the right (that is, \(x \text{**} y\text{**}z=x \text{**} (y\text{**}z)\text{ and not }(x \text{**} y)\text{**}z\)), the rule defining power does this\(<power>\text{ }:=\text{ }<factor>\text{ }|\text{ }<factor>\text{**} <power>\)
and not
\(<power>\text{ }:=\text{ }<factor>\text{ }|\text{ }<power>\text{**}<factor>\)
Since multiplication/division are left associative (that is, \(x \text{*} y\text{*}z=(x \text{*} y)\text{*}z\)), the rule defining a term takes this into account by specifying its recursion on the right of the operators like so;\(<term>\text{ }::=\text{ }<power>\text{ }\\|\text{ }<term>*<power>\text{ }\\|\text{ }<term>/<power>\)
Also, addition and subtraction are left associative (that is, \(x \text{+} y\text{+}z=(x \text{+} y)\text{+}z\)), the rule defining an expression takes this into account as seen below\(<expression>\text{ }::=\text{ }<term>\text{ }\\|\text{ }<expression>+<term>\text{ }\\|\text{ }<expression>-<term>\)

Feedback from the Customer through Customer Satisfaction Survey (CSS) form is obtained once in a half
year. Is this statement True or False?
Answers
The statement "Feedback from the Customer through Customer Satisfaction Survey (CSS) form is obtained once in a half year" is insufficiently clear to provide a definitive answer.
It depends on the specific practices and policies of the organization conducting the customer satisfaction survey.
In general, the frequency at which organizations collect feedback through customer satisfaction surveys can vary widely. Some organizations may choose to conduct surveys annually, while others may opt for more frequent intervals such as quarterly, monthly, or even more frequently. There is no standard rule or requirement dictating how often customer satisfaction surveys should be conducted.
The frequency of obtaining feedback from customers is often determined by various factors, including the nature of the business, the industry, the size of the customer base, and the resources available for survey administration and analysis.
Additionally, organizations may consider the desired level of granularity in tracking customer satisfaction and the need for timely feedback to drive improvements.
Therefore, without specific information about the organization in question and its customer feedback practices, it is not possible to definitively label the statement as true or false.
The frequency of obtaining feedback through a customer satisfaction survey can vary from organization to organization and is ultimately determined by their specific strategies and objectives.

Which of the following application delivery methods requires Internet access?

Explanation:
A Quicksort (or Partition Exchange Sort) divides the data into 2 partitions separated by a pivot. The first partition contains all the items which are smaller than the pivot. The remaining items are in the other partition. You will write four versions of Quicksort:
• Select the first item of the partition as the pivot. Treat partitions of size one and two as stopping cases.
• Same pivot selection. For a partition of size 100 or less, use an insertion sort to finish.
• Same pivot selection. For a partition of size 50 or less, use an insertion sort to finish.
• Select the median-of-three as the pivot. Treat partitions of size one and two as stopping cases.
As time permits consider examining additional, alternate methods of selecting the pivot for Quicksort.
Merge Sort is a useful sort to know if you are doing External Sorting. The need for this will increase as data sizes increase. The traditional Merge Sort requires double space. To eliminate this issue, you are to implement Natural Merge using a linked implementation. In your analysis be sure to compare to the effect of using a straight Merge Sort instead.
Create input files of four sizes: 50, 1000, 2000, 5000 and 10000 integers. For each size file make 3 versions. On the first use a randomly ordered data set. On the second use the integers in reverse order. On the third use the
integers in normal ascending order. (You may use a random number generator to create the randomly ordered file, but it is important to limit the duplicates to <1%. Alternatively, you may write a shuffle function to randomize one of your ordered files.) This means you have an input set of 15 files plus whatever you deem necessary and reasonable. Files are available in the Blackboard shell, if you want to copy them. Your data should be formatted so that each number is on a separate line with no leading blanks. There should be no blank lines in the file. Even though you are limiting the occurrence of duplicates, your sorts must be able to handle duplicate data.
Each sort must be run against all the input files. With five sorts and 15 input sets, you will have 75 required runs.
The size 50 files are for the purpose of showing the sorting is correct. Your code needs to print out the comparisons and exchanges (see below) and the sorted values. You must submit the input and output files for all orders of size 50, for all sorts. There should be 15 output files here.
The larger sizes of input are used to demonstrate the asymptotic cost. To demonstrate the asymptotic cost you will need to count comparisons and exchanges for each sort. For these files at the end of each run you need to print the number of comparisons and the number of exchanges but not the sorted data. It is to your advantage to add larger files or additional random files to the input - perhaps with 15-20% duplicates. You may find it interesting to time the runs, but this should be in addition to counting comparisons and exchanges.
Turn in an analysis comparing the two sorts and their performance. Be sure to comment on the relative numbers of exchanges and comparison in the various runs, the effect of the order of the data, the effect of different size files, the effect of different partition sizes and pivot selection methods for Quicksort, and the effect of using a Natural Merge Sort. Which factor has the most effect on the efficiency? Be sure to consider both time and space efficiency. Be sure to justify your data structures. Your analysis must include a table of the comparisons and exchanges observed and a graph of the asymptotic costs that you observed compared to the theoretical cost. Be sure to justify your choice of iteration versus recursion. Consider how your code would have differed if you had made the other choice.

Write the statement that shows the average population of 'Poland', 'Germany' and 'Denmark'
Answers
To calculate the average population of 'Poland', 'Germany' and 'Denmark' in Python: (populations sum) / 3.
To write a statement that shows the average population of 'Poland', 'Germany' and 'Denmark', we first need to have access to the population data for these countries.
Assuming we have a list or dictionary of the population values, we can use the built-in Python function sum() to calculate the total population, and then divide by the number of countries to get the average.
Here's an example of what the code might look like:
# assuming we have population data in a dictionary
population_data = {'Poland': 38000000, 'Germany': 83000000, 'Denmark': 5800000}
# calculate the average population
average_population = sum(population_data.values()) / len(population_data)
# print the result
print("The average population of Poland, Germany, and Denmark is:", average_population)
This code will output a message to the console that shows the calculated average population value.
