- 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.Can you help me solve the section Using Powershell. I need help writing out the commands.How can I take out data from the get request in JavaScript.

- Write a bash script called happy_countries.sh that lists out the names of the countries reported by 2022 World Happiness Report ranked by the happiness. Your script will retrieve the information directly from the following wikipedia page, https://en. wikipedia.org/wiki/World_Happiness Report. However, parsing the data directly from HTML Homework 1 is a headache. Luckily, you can request the page in an alternative format (raw wiki format) by us- ing (https://en.wikipedia.org/wiki/World_Happiness_Report?action=raw). Notice the suf- fix ?action=raw. Finland Norway Denmark Iceland 3 To keep things simple, you are to list only top 5 countries. For this task, you may only use the following tools: curl, sed, awk, grep, tr, cut, sort, head, tail.

- shell script needed for the following I have two files in the same directory: "host_list" and "known_hosts". host_list contains a list of servers. known_hosts contains the keys for each of the servers in host_list. I want the script to take from host_list a server name and check (grep) all keys containing that server name in known_hosts. If the resulting keys contain 'sample' in the url, keep those keys. Otherwise delete the rest. Here's an example: In host_list, we have two servers: be3abcd3 and be3efgh4.We check for mentions of be3abcd3 in known_hosts. That results in:be3abcd3.300.200.100.50andbe3abcd3.sample.com The script will delete be3abcd3.300.200.100.50 and keep be3abcd3.sample.com, as that contains 'sample' in the url.need a trading bot coded in python. The bot has key, which is a token. If a user buys/has our token in his/her wallet, he/she can log in to the bot. The bot should exchange(buy/sell) the top crypto currencies.PYTHON!!!!! Write a script that decrypts a message coded by the method used in Project 6 Method used in project 6: Add 1 to each character’s numeric ASCII value. Convert it to a bit string. Shift the bits of this string one place to the left. A single-space character in the encrypted string separates the resulting bit strings. An example of the program input and output is shown below: Enter the coded text: 0010011 1001101 1011011 1011011 1100001 000011 1110001 1100001 1100111 1011011 1001011 000101 Hello world!

- 1. Use the random substitution cipher below to encrypt the following message: Virtual Event. Write the final code in 4 letter blocks. Original A B |C|D EF GHIJKLMN ОР QRST UVW XYZ Maps to LFNIRD TPSE QJAY G MZB XK WU CVHO Answer:Need help with this code: You will write a client-server system for writing/storing notes. Each note has an ID (integer), a title (short text), and a body (long text). A client can have three kinds of requests to the server: upload a note, download a note (given its ID), and search for a note (given a keyword). In the case of search, the server will return a list of IDs and titles of notes whose titles contain the keyword. Design the database to store the notes. Design the Ul of the client. • Write code to implement the system. • You should use design patterns as in the Store Management System: 3-layer; Model-View-Controller; Singleton, Adapter. 1. StoreManager code public class StoreManager { private static StoreManager instance = null; private RemoteDataAdapter dao; private ProductView productView = null; public ProductView getProductView() { return productView; } private ProductController productController = null; public static StoreManager getlnstance() { if (instance == null)…USING KEIL PLEASE.. Ciphers use many bitwise operations for cryptography. Write an ARM assembly program to use ciphers. See the steps below to implement the cipher. In this program, you will implement a "Symmetric Encryption". Create three variables, Plaintext, Key, and Cipher (5 Points) For encryption, design a key value, assign the last nonzero number of your student ID (#900 number) in a variable called “Key” (5 Points) For example: if your 900 number is 90012450. Assign 5 to the variable Key and use it as the Key for encryption. Use this link for the Links to an external site.video to understand Symmetric Key Cryptography and implement that for encryption and decryption. For the variable Plaintext, assign any four-letter word. Encrypt the plaintext using the value in Key and store the encrypted text in the variable Cipher. Test the encryption by decrypting and storing the decrypted text into register R5. Provide comments to each statement
