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

- Question 4 (PROGRAMMING) A classification algorithm is a kind of machine learning algorithm which is used to assign a label to an object, based on the knowledge of similar objects. 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 returned array should end with a '/0' to form a valid string.The array returned should be dynamically allocated, no larger than twice the character length of the file. It needs to be done in one I/O pass and dynamically allocate more memory for larger input.The function cannot use any functions that would determine the size of the file. No fstat() or fseek() or anything like that. It also cannot allocate or copy memory on each loop iteration. It cannot use realloc(), only malloc() and free(). It should use linear time and space and take up no more memory than 2 times the characters in it.arrow_forward
- Pls help ASAP, program C (Loops)arrow_forwarduse code to develop a C program that gets a source file name from a user. If the file does not exist, it will generate a proper error and exits. If the file exists, it also gets the name of two files from the user, say destination1 and destination2. These files don't need to exist as they are files that need to be written to. The program then reads the source file line by line. If the line starts with an uppercase and ends with a lower case, it copies that line to dest1 (first destination file) If the line starts with a lowercase and ends with a dot ('.'), it copies that line to dest2 (second destination file) If neither of the above hold, the program discards that line (doesn't copy it anywhere) The program then displays a report mentioning how many lines were copied into each destination file. Don't forget to close all the files.

Objective After performing this activity, you should be able to 1. Perform operations on directories in assembly language. II. Introduction This experiment covers a number of extended DOS services for disk operations introduced by DOS 2.0 and 3.0. Many of these services are much simpler than the original DOS services are generally recommended. These operations involve the use of an ASCIIZ string to initially identify a drive, path and filename; a file handle; and special error return codes. Int21H Service 39H: Creating a directory Function 39H creates a subdirectory, just like the DOS command MD For example, diname, dh 'C:\TASM',0 mov ah, 39h lea dx dirname int 21h A successful operation creates the subdirectory TASM in drive C. An error sets the carry flag and returns code 03 (path not found or invalid path) or 05 (access denied or directory already exists) in register AX.
