- Python: if possible answers in one line of code def name_sort(staff): ''' Question 2 You are given a list of Georgia Tech staff members- each with a first and last name separated by a space, and need to sort them alphabetically by last name for a directory. However, the person who provided you the list did not proofread the records and accidentally misspelled some of the names. You can identify which ones have typos just by looking at the first letter of the first name. - First, sort the list alphabetically by the last name. - Remove any members whose first name starts with "Q" or "X". - Return the resulting list. Args: staff (list) Returns: list >>> name_sort(['Damon Williams', 'Xngel Cabrera', 'George Burdell', 'Brett Key', 'David Joyner', 'Qon Lowe']) ['George Burdell', 'David Joyner', 'Brett Key', 'Damon Williams'] ''' # print(name_sort(['Damon Williams', 'Xngel Cabrera', 'George Burdell', 'Brett…*Student information is being held in a data area, where each student record has the following format: The first nine bytes are the student number, held in ASCII The next byte is the course mark The next word is the section identifier 10009. There are well over three hundred such student records that have been loaded sequentially into memory starting at address $10000. The last record loaded is a dummy record with a section identifier of $FFFF, to show the end of the rècords. If a2 has the address of a student record, what is the location of the next record in the array / data area. Explain your answer.A temperature file consists of five records, each containing a temperature in degrees Fahrenheit. A program is to be written that will read the input temperature, convert it from degrees Fahrenheit to degrees Celsius and print both temperatures in two columns on a report. Column headings, which read ‘Degrees F’ and ‘Degrees C’, are to be printed at the top of the page. What ist he best solution algorithm to successfully implement the above question?
- 3. Laramie Park District has files of participants in its summer and winter programs this year. Each file is in participant ID number order and contains additional fields for first name, last name, age, and class taken (for example, Beginning Swimming). a. Design the logic for a program that merges the files for summer and winter programs to create a list of the first and last names of all participants for the year in ID number order. b. Modify the program so that if a participant has more than one record, the participant's ID number and name are output only once. c. Modify the program so that if a participant has more than one record, the ID number and name are output only once along with a count of the total number of classes the participant has taken.A file has r=20000 STUDENT records of fixed-length. Each record has the following fields: NAME (30 bytes), SSN (10 bytes), ADDRESS (40 bytes), PHONE (9 bytes), BIRTHDATE (8 bytes), SEX (1 byte), MAJORDEPTCODE (4 bytes), MINORDEPTCODE (4 bytes), CLASSCODE (4 bytes, integer), and DEGREEPROGRAM (3 bytes). Suppose the block size is 512 bytes. (a) Calculate the record size R in bytes. (b) Calculate the blocking factor (number of tuples per block) and the number of blocks required. (c) Calculate the average block accesses it takes to find a record by doing a linear search on the file. (d) Assume the file is ordered by SSN; calculate the block accesses takes to search for a record given its SSN value by doing a binary search.In C++, Query the user for the name of a file. Read the words from the file and report the number of words whose last letter is 'a', the number whose last letter is 'b' and so on, irrespective of case.
- Exercise 6. Create a dictionary from a Text File: When a program incorporates a large dictionary, the dictionary is usually created from a file, such as a text file by using dict function to convert a list into a dictionary. Whenever a word in the original sentence is not a key in the dictionary, the get method places the word itself into the translated sentence. The file “Textese.txt” contains a word and its translation into textese. Write a program to create a dictionary with the file, ask the user to enter a simple sentence then translate it into textese. Define two function createDictionary (filename) and translate (sentence, dictionary). Then define a main function to test your functionsWrite a program in C++ that creates a file. Write this data into that file column wise as a header. Then keep adding data in colum wise format. The program should check if there is data in the file and then write the data in the next row. First add: TIME DAY MONTH YEAR Then check the file and add: 01:25 07 JUNE 2008 Then check again the file and add this in next row: 14:00 30 MARCH 2019Create a program in C language for reading and writing student records. Submit all necessary source codes and files to run this program (it is recommended to compress all files and submit a single file). First create text file "student_records.txt". The file should look like: Name Surname Quiz 1 Quiz 2 Quiz 3 Ada Lovelace 93 88 97 Babbage Turing Нopper Charles 26 80 70 Alan 74 85 92 Grace 99 87 100 a. Read the file contents and load them into an array of Record structs. b. The record struct has the member variables: o char array name o char array surname o int quiz_1 o int quiz_2 o int quiz_3 c. Write a function that calculates a students quiz average. The function takes a Record struct and returns a double. d. Create two new records for students inside your main program. e. Create a new text file with the new records to a a file called "student_records_new.txt"
- Let A and B two text files, containing some binary lines between of length 1...N. Where N is the line with the maximum number of characters, 1 the minimum number of characters in each line. Design a Python3 function to compare each line of the files, character by character, and if there is a match of the characters, create a variable representing the similarity between the lines of each file, and return that similarity variable measures the similarity between two files.Suppose a file contains student's records with each record containing name and age of a student. Write a program to read these records and display them in sorted order by name. Use C language to write a program.In The Readline Technique, on page 179, you learned how to read somefiles from the Time Series Data Library. In particular, you learned aboutthe Hopedale data set, which describes the number of colored fox fur peltsproduced from 1834 to 1842. This file contains one value per year perline.a. Write an outline in English of the algorithm you would use to readthe values from this data set to compute the average number of peltsproduced per year.b. Translate your algorithm into Python by writing a function namedhopedale_average that takes a filename as a parameter and returns theaverage number of pelts produced per year.
