A group of computer scientists wants to create a fixed-length compression algorithm. The simplest way to achieve compression is to use a fixed-length code generator. The idea behind this type of code generator is to assign a fixed-length bit sequence to each symbol of the alphabet. As part of this group of computer scientists, your goal is to write a program to determine the alphabet used by the message to be compressed (set of different characters in the input message), and the frequency of each symbol in the alphabet, using conditionals, loops, and arrays.

Answers

Answer 1

Answer:

Here the code is given as follows,

Explanation:

OUTPUT:  

Message: AAAABBBCCDDDDDDDE  

Number of symbols in the alphabet = 5  

Characters in the alphabet = A,B,C,D,E  

Number of bits per symbol = 3

A student is conducting an experiment in which he adds an inhibitor to an enzyme-catalyzed reaction that contains alkaline phosphatase. When the student first adds the inhibitor, the reaction rate decreases, however, he can return the reaction rate to normal by adding a large quantity of substrate. What type of inhibitor is the student using, non-competitive or competitive?

Answers

Answer:

competitive

Explanation:

An inhibitor is a substance that hinders the action of an enzyme. An inhibitor may be competitive or non competitive.

A competitive inhibitor is an inhibitor that is very similar to the substrate hence it binds to the enzyme instead of the substrate. A noncompetitive inhibitor binds to a site that is different from the active site. This site is called an allosteric site.

If we look at the experiment described in the question, the reaction rate decreases upon addition of the inhibitor. This effect is reversed by adding a large quantity of substrate.

The implication of this observation is that the enzyme and the inhibitor compete for the active site on the substrate.

Hence the inhibitor is a competitive inhibitor.

competitive inhibitor is the students using

A palindrome is a string that reads the same from left to right and from right to left. Design an algorithm to find the minimum number of characters required to make a given string to a palindrome if you are allowed to insert characters at any position

Answers

Answer:

Explanation:

The following code is written in Python. It is a recursive function that tests the first and last character of the word and keeps checking to see if each change would create the palindrome. Finally, printing out the minimum number needed to create the palindrome.

import sys

def numOfSwitches(word, start, end):

   if (start > end):

       return sys.maxsize

   if (start == end):

       return 0

   if (start == end - 1):

       if (word[start] == word[end]):

           return 0

       else:

           return 1

   if (word[start] == word[end]):

       return numOfSwitches(word, start + 1, end - 1)

   else:

       return (min(numOfSwitches(word, start, end - 1),

                   numOfSwitches(word, start + 1, end)) + 1)

word = input("Enter a Word: ")

start = 0

end = len(word)-1

Assume that a file contains students’ ids, full names, and their scores (Assignments grade, quizzes grade, Midterm grade, Practical exam grade, and final exam grade) (each column is separated by $). You are required to write a C program to do the following:



• Using the concept of parallel arrays create records for students with above attributes (id, full name, score).(you are not allowed to use structure)

• Ask the user to enter the input file name and read it (suppose that, there are different files you could read data from). Read the data from the file and store it in record for students, which has IDs, Names, and Scores. The IDs should be declared as integers, the Names as a two-dimensional array of characters and the Scores as doubles. Assume that the maximum length of full name of any student is 50 characters. Also, you may assume that there will be No more than a 1000 student records in the file.

• Calculate the final grade as the flowing:

Grade= (Assignment)*15%+(Quizzes) *15%+(Midterm exam) *25%+(Practical Exam)

*10%+(Final) *35% Assuming that data in files are arranged in same order of the above equation with respect to grades



Hint: read form file, calculate the final score, and store it in the record before going to the next step.

• Display the following menu to the user and read the entered choice:

1) Sort data in ascending order according to students’ IDs and then display it.

2) Sort data in ascending order according to students’ names and then display it.

3) Sort data in descending order according to students’ scores and then display it.

Note: After running any of the above menus items, ask the user if he/she would like to save the current result, if so, prompt user to enter file name.

4) Ask the user to enter a student ID and display his score

5) Ask the user to enter a student name and display his score

6) Exit the program











 The program should keep displaying the menu until the user selects to exit from the program.

Implement each of the first five menu options as a separate function.

Answers

Answer:

The modified program in Python is as follows:

triangle_char = input('Enter a character:\n')

triangle_height = int(input('Enter triangle height:\n'))  

for i in range(triangle_height):

   print(triangle_char * (i+1))

Explanation:

This gets the character from the user

triangle_char = input('Enter a character:\n')

This gets the height of the triangle from the user

triangle_height = int(input('Enter triangle height:\n'))  

This iterates through the height

for i in range(triangle_height):

This prints extra characters up to the height of the triangle

   print(triangle_char * (i+1))

Here's the modified program that incorporates the requested changes:

python

Copy code

triangle_char = input('Enter a character:\n')

triangle_height = int(input('Enter triangle height:\n'))

print('')

for i in range(1, triangle_height + 1):

   line = triangle_char * i + ' ' * (triangle_height - i)

   print(line)

This program uses a loop to iterate from 1 to triangle_height. In each iteration, it creates a line by concatenating triangle_char repeated i times with spaces (' ') repeated (triangle_height - i) times. The resulting line is then printed.

For example, if the user enters % as the character and 5 as the height, the output will be to make sure to maintain the indentation properly in your code for it to work correctly.

Option c (a <= b && b > c) and Option e (a < b && b >= c) is the correct answer.

According to the question, the given expression is:

⇒ !(a > b || b <= c)

There will be some changes occur between the values such as:

! = It becomes normal> = It becomes <|| = It becomes &&

So that the expression will be:

⇒ a < b && b >= c

Other choices are not connected to the expression or the rules. So the above two alternatives are the correct ones.
