(c) Write a Haskell program that:
• Reads two files, called "input1.txt" and "input2.txt".
• Interleaves the lines of the two files.
• Writes the result to a file called "output12.txt" .
You may make use of any functions in the Reference (pp5-7).

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:

Using import numpy as np, import sys and def functions, create a code that accepts input from a text file, solves matrix operations (add, scalar multiply, multiply, or transpose), and prints output to a text file. Note: If Matrix A and Matrix B are ordered to be added but the dimension of Matrix A is not equal to the dimension of Matrix B, print "Matrix addition cannot be performed; dimensions are unequal."Note: If Matrix A and Matrix B are ordered to be multiplied but the number of columns of Matrix A is not equal to the number of rows of Matrix B, print "Matrix multiplication cannot be performed; number of columns of Matrix A is not equal to number of rows of Matrix B."Please annotate the significant parts.
Format of the input from text file:First Line: type of operation (add, multiply, scalmultiply, or transpose)Second Line: matrix A dimension (example: if 3 rows and 2 columns, type 3 2)Third Line: matrix A elementsFourth Line: matrix B dimension (or the scalar number…

Note: if the file already exists, it will be erased and overwritten without warning. For example, COP4338$ ls > 1COP4338$ sort myshell.c > 2Note that you're not supposed to implement the Unix commands (ls, sort, ...). You do need to implement the shell that invoke these commands and you need to "wire" up the standard input and output so that they "chain" up as expected. >> - Append standard output from a command to a file if the file exists; if the file does not exist, create one.

- 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.

- (5.1) In the context of designing a system that offers a file management capability, e.g., OneDrive, there are some constraints on the acceptable file names. The following three characters {*,$, :} in addition to spaces are not allowed in file names. If any of these four characters appears in a file name, it is replaced by a hyphen (-). Examples: "new file" → "new-file" "important$file" → "important-file" "abc$def gh:ij*klm.txt" → "abc-def-gh-ij-klm.txt" "exam.doc" →→ "exam.doc" i.

Below is the data to be displayed At present, most of the dynamic sign language recognition is only for sign language words,the continuous sign language sentence recognition research and the corresponding results are less, because the segmentation of such sentence is very difficult. In this paper, a sign languagesentence recognition algorithm is proposed based on weighted key frames. Key frames can be regardedas the basic unit of sign word, therefore, according to the key frames we can get related vocabularies, and thus we can further organize these vocabularies into meaningful sentence.
