Write a shell script to read a sequence of zeros and ones as a binary number and return the corresponding value. It will continue to accept digits until a non-binary character is received. For example: '1', '0', '1','' will result in the value 5 being returned. And the sequence '1', '1','' will result in the value 3 being returned. How to submit: 1. Save the source file of the code. 2. Take screenshot of the output of the program.

Write a high-security program in C that reads positive integers from a file "/challenge/numbers.txt" in the same directory as the program and outputs the biggest and smallest number.        Input (from numbers.txt):            100            45            12            0            42            922            2        Output:            922            0

Write a program that prompts the user to enter afile name and displays the occurrences of each letter in the file. Letters are caseinsensitive. Here is a sample run:Enter a filename: Lincoln.txt ↵EnterNumber of As: 56Number of Bs: 134...Number of Zs: 9

Write a program in C to decrypt a cipher text using Caesar Cipher substitution method.Plain text was first encrypted with a Cipher Key within the range 1 to 26 and then encrypted then encrypted with key -1 (minus 1).Find the first key and write the key numbers and the decrypted plain text into text mode file "done.txt" using your program

Draft a Python program that prompts the user for the name of two files. The script should copy the lines of text from the input file to the output file, numbering each line as it goes. The line numbers should be right-justified in 4 columns, so that the format of a line in the output file looks like this example:

could you please code this on notepade.

Professor Potter, a punning pedantic, practices puzzling her students. She has left a secret message, of unknown length, encoded in a file for you to unravel. The setup is simple: each line of the file contains one char and one non-negative integer. The key to reading the message is organizing the characters in the proper order. The integer indicates the position of the character within the message. For example: e 2 b 1 a 3 h 5 c 4 spells 'beach' when unraveled. Write a program that will: Ask the user for the name of a file Check to see that the file exists and contains some data. Open and read this file exactly once Using your MessageDecoder class, unravel and display the message Offer to do it again on another file Required classes: You will create and submit 2 classes: MessageDecoder class: Responsible for converting a scrambled message file into plain text. Contains a public method getPlainTextMessage() that returns the String object. The scrambled file must be scanned only once…
