For this programming assignment I want you to write a program that calculates bigram frequencies for a set of text.
Your program should assess the text and calculate the frequency of word pairs that occur throughout the entire file.
Your program should ignore case (meaning "the dog" and "The dog" should count as the same phrase).
Your program should write out the frequency count for each uniquely occurring bigram to a file with the count and the bigram separated by a tab.
As an example, bigram frequencies for the following sentence are:
Sentence: The dog and the cat do not get along because the dog is mean to the cat and the cat is aloof to the dog.
Bigrams:

- Problem 2 (Cipher module)• Create a Python file named cipher_module.py with functions to encode and decodestring inputs using the basic Caesar cipher (see here for more informationhttps://en.wikipedia.org/wiki/Caesar_cipher). This cipher is a basic encryptiontechnique that supports encoding and decoding operations on strings.• The encoding operation replaces each character in a string with another charactersome fixed number (shift) of positions down the ASCII table. The string can beencoded using any characters on the ASCII table and no need to use the circular list(where ‘Z’ is followed by ‘A’) image shown below. Your module must have a functionnamed encode() that takes a string and an integer shift (can be positive or negative)as parameters and returns the encoded string using the shift value. This module must Page 3 of 4also have a second function name decode() that takes an encoded string and aninteger shift as parameters and returns the decoded string.

Suppose a file contains 100 bytes of data. A program successfully opens it for both reading and writing (i.e., passing the mode O_READWR to open()), and gets back a file descriptor number fd. a. The program, which has a 40-byte buffer, issues a call to read() for 40 bytes. It processes that data, and then repeats the call. Both calls return the exact amount requested. Then it issues a third read, again requesting 40 bytes. What value will it return? (Assume no other program has the file open.) b. Next the program calls write (fd, buffer, 40), and the call returns 40. Then it issues another read() call for 40 bytes. What value does that call return? c. Suppose the programmer needs to read back the 40 bytes just written. First it must use 1seek() to reposition the file pointer. What parameters should it invoke 1seek () with so that the next read call will return the 40 bytes just written?arrow_forward
- (1) Create a cpp file Array Operations under Source files folder. Write a program in C++ to declare an array called mark. This array will store marks of an assessment like practical, assignment or test for 16 students. Therefore, the size of the array should be 16. a. Number of available marks are 10 for ten students, however there are 16 students, therefore, the remaining marks will be read into the program while the program is running. For now, initialize the array with given marks. 7.3 8.6 10.65 16.4 13.5 6.35 17.3 4.4, 8.5, 12.7 b. With reference to unavailability of remaining 6 marks in part a, write codes to read these remaining six marks and add them at the end as you read. c. Write codes to count the numbers above the average. d. Write codes to determine the highest mark a student scored. e. Display all the important data and results with descriptive relevant labels.

Program Requirements: There should be 2 separate programs for write and Read. mknod() - Creates the named pipes Define the length of your message on a buffer Define your descriptor Use the open() O_WRONLY O_RDWR In your program, consider the following: Use the read() function to read nbytes from the file associated with the andle, and places the characters read into the buffer. Make sure you indicate the number of characters on the reader output. Use gets() to read the characters from stdin() that are stored in your buffer.

Write a C program able to implement the classification algorithm 1-NN. The program receives as input two files and , whose names are passed as arguments from the command line: The file contains a set of N objects (one for each line), each one with the corresponding label. This file is used to train the classification algorithm, which learns how to recognize the known objects. Each line of the file contains the name of the object represented as a string at most 5 characters, a set of M real numbers T1 T2 T3 .. TM, followed by an integer L. The space character is used to separate the elements. The M real numbers are the features that represents an object. The integer L is the object label. The file contains a set of objects to be classified. The format is similar to the file, but the number of rows is NOT…arrow_forward
- Purpose: To practice write a list of records to a tabular text file Degree of Difficulty: Moderate. In this question, your program will define a function named fnWriteState(), with two input parameters: · A list of records (the list of state of all days) · A string of a path name of the output file And there is no return values of this function. In this function, your program will write the list of state to a tabular file. It is notable that the output file should locate in the same folder of the a6.py file. In the state output file, the first line is names of the time, S, I and R. And lines from the second to the last line of the output file contain every day's state of S, I and R in the list of state, and also with the item of time (indicates the index of the day). Each record in the list of state will be written in one line. And the items of each line will be separated by commas. Basically, the format of the state output file is the same as the state input file. But in the state…arrow_forward2. Peter likes singing songs and playing music with an electric piano.
