Concept explainers

Stack operations

A stack is a linear data structure that follows certain order to perform the operation; the order will be LIFO (Last In First Out) data structure. In the stack data structure elements/items are removed and added only from the top. The topmost stack item/element is pointed by the top pointer and the element which is added to the stack first will get deleted at the last.

Question

"Histogram," takes an integer "n," and two integers "left
and right," and uses "StdDraw" to plot a histogram of
the count of the numbers in the standard input stream
that fall in each of the n intervals defined by dividing (
left, right) into n equal - sized intervals. Note: The
program is to read the values from an input file whose
first line would contain "n," "left," and "right" values.
The remaining lines would contain the sequence of
integer values. A sample run would be as follows.
Please note that the program would read the input data
from a file whose name is specified via the redirection
operator "<". > more data.txt

java Histogram < data.txt It should plot a histogram
where the x-axis points are 40, 50, 60, 70, 80 and the
intervals are 40-50, 50-60, 60-70, 70-80. The
height of the rectangles for the intervals should be
3, 4, 7, 6 respectively.

I am trying to read in a text file called "lines.txt" that holds an entire dictionary of words with multiple words on each line. I am supposed to find the longest word in the file and the line number it is on. So far I know that I am supposed to have a line counter when initializing the first get line() to 1 but I am confused on how to parse through it.
Write a program that computes and prints the average of the numbers in a text file. You should make use of two higher-order functions to simplify the design. Ask the user for the name of the .txt file that contains the list of numbers. Include your code as usual in a .txt AND .py file. Create and use a .txt file to test your code using the numbers 78, 54, 22, 90, 15, 7.
i have already asked this question and the answer did not work for me: Write a program that first reads in the name of an input file and then reads the file using the csv.reader() method. The file contains a list of words separated by commas. Your program should output the words and their frequencies (the number of times each word appears in the file) without any duplicates. Ex: If the input is: input1.csv and the contents of input1.csv are: hello,cat,man,hey,dog,boy,Hello,man,cat,woman,dog,Cat,hey,boy the output is: hello 1 cat 2 man 2 hey 2 dog 2 boy 2 Hello 1 woman 1 Cat 1 Note: There is a newline at the end of the output, and input1.csv is available to download.
13. Write function quote() that takes as input the name of a file (as a string) and anindex i (as an integer). The file will contain quotes, one per line. The function shouldopen the file, read the file, close the file, and return the i-th quote (i.e. the i-th line in thefile), assuming that the quote numbering starts at 0. Test your solution onfile Wilde_Quotes.txt.>>> quote("Wilde_Quotes.txt", 5)'At twilight, nature is not without loveliness, thoughperhaps its chief use is to illustrate quotations from thepoets.\n'>>> quote("Wilde_Quotes.txt", 0)'A little sincerity is a dangerous thing, and a great dealof it is absolutely fatal.\n'>>> quote("Wilde_Quotes.txt", 23)'Patriotism is the virtue of the vicious. \n'>>>
PYTHON: I need to get the avg statement out of the loop so that the output prints correctly. Any suggestions. Write a program that reads the student information from a tab separated values (tsv) file. The program then creates a text file that records the course grades of the students. Each row of the tsv file contains the Last Name, First Name, Midterm1 score, Midterm2 score, and the Final score of a student. A sample of the student information is provided in StudentInfo.tsv. Assume the number of students is at least 1 and at most 20. The program performs the following tasks: Read the file name of the tsv file from the user. Open the tsv file and read the student information. Compute the average exam score of each student. Assign a letter grade to each student based on the average exam score in the following scale: A: 90 =< x B: 80 =< x < 90 C: 70 =< x < 80 D: 60 =< x < 70 F: x < 60 Compute the average of each exam. Output the last names, first names, exam…

Note: A input file named "input.txt" is attached with this test. Read the file as input and save the output in the required format in a separate file named “output.txt". Given X is an N-digit odd positive integer such that X is divisible by 3 but not by 9. NOTE: There should not be any leading zeros in X. 003 is not a valid three-digit even integer. Input Format: • The first line of input contains a single integer T, denoting the number of test cases. • The first and only line of each test case contains a single integer N, denoting the numbe of digits in X. Output Format: For each test case, output a single line containing N-digit even positive integer X, such that X is divisible by 3 but not by 9.

Use the functions from the previous three problems to implement a pro-gram that computes the sum of the squares of numbers read from a file. Your program should prompt for a file name and print out the sum of thesquares of the values in the file. Hint: Use readlines ()
pls code in pythonplagiarism: This Boolean function takes two filenames. If any line occurs in both files, return True.If not, return False. I suggest using nested loops. With nested loops, we call the loop that is in thebody of the other loop, the "inner loop". The loop that contains the inner loop is the "outer loop". Openthe second file inside the outer loop:for line1 in file1:file2 = open(fname2)for line2 in file2:Python only lets you read the file once per open, so you need this order of instructions. Make sure yourreturn False is outside of both loops. Otherwise, you will only compare the first two lines of thefiles. Make sure you close the file that gets read repeatedly after the inner loop but still inside the outerloop.Here is some (more complete) pseudocode to get you started:open file 1for line1 in file 1open file 2for line2 in file 2:if line1 == line2:return Trueclose file 2return False
You are not allowed to use strings, cstrings!!! A C++ Program: We have obtained some files that are encoded with a simple method of writing the text from end to beginning. We therefore need a program that reads a file named codedfile.txt that is 500 chars or less and generates a file call clearfile.txt that has the characters stored in revers order. For example, if codedfile.txt contains the characters dlrow olleh, then after running the program clearfile.txt should contain hello world. Do not use strings or cstrings for reasons explained please!
6. Write a program that will randomly generate 500 integer numbers in the range -249 to 250. Write thosenumbers in a text file named “in.txt”. Now Sort (in ascending order) all the integer numbers in the file “in.txt”using Buuble Sort. Save the sorted output into another text file named “out.txt”. (Try to write separatefunction for SWAP and BUBBLE_SORT and call them from main function.)
Suppose you are given a text file that contains the names of people. Every name in the file consists of a first name and last name. Unfortunately, the programmer that created the file of names did not guarantee that each name was on a single line of the file. Read this file of names and write them to a new text file sorted according to first name, one name per line. For example, if the input file contains Ed Marston Bob Jones Jeff Williams Fred Charles The output file should be Bob Jones Ed Marston Fred Charles Jeff Williams Use arrays to solve the problem.
