COMPUTER SCIENCE

IS NOT

writing a program that

calculates the answers to

the math problems in your

homework.

writing a program to

automatically post nice

comments on your friends’

pictures.

doing your math homework

on your school’s laptop.

commenting on the latest

picture your friend posted.

All the examples in the

IS NOT list only

use

technology, while

the examples in the

new technology.

DON'T JUST

PLAY ON YOUR

PHONE.

PROGRAM IT!

THE FIVE CONCEPT AREAS OF

COMPUTER SCIENCE

Computer science can be divided into five concept areas

(main parts) of study

1. Computing

Systems

Computing systems are the

machines that run programs

and process information. Examples are desktop computers,

laptops, and phones. Many electronic devices are run by

PROGRAMS and have small built-in computers. For example,

dishwashers, TVs, smart watches, and even some light bulbs.

2. Algorithms and

Programming

ALGORITHMS and

programming involve writing

the programs (code) that tell

computers what to do. Programs

can be very complex

like iTunes,

Safari, Chrome, or Roblox

following many different

instructions. They can also be

simple, like a program that

only prints out the message

“Hello, World!”

ALGORITHM

A list of steps or instructions

written in human language

that tells a person how to

complete a task.

PROGRAM

A set of instructions

(or an algorithm) that

has been translated into

commands a computer

can understand (

code).

Writing a program is sometimes broken up into two steps:

STEP 1: The computer scientist

makes a list of step-by-step

instructions for what she wants

her program to do.

STEP 2: The computer scientist

translates her instructions into

a language (code) the computer

can understand. Now the

algorithm is a program.

Algorithm

Computers are powerful, but they really aren’t that smart.

They can only do what they're told. Programs give

computers the instructions they need to work.

Programming

3. Data and Analysis

DATA and ANALYSIS refer

to collecting, storing, organizing,

and studying facts to help us

understand what the data means.

For example, in a personality test

program, we would want to collect

answers to questions (such as

“Do

you like having lots of friends

over to play games?” or “How do

you like to spend your free time?”), store the answers, and

study them to understand someone’s personality. Another

simple use of data might be to collect and store the score

in a video game so that we can see if a player has won,

or who the highest scorer was.

Computers are great at storing, sharing, and calculating

huge amounts of data. This makes them perfect for

analyzing data.

4. Networks and the Internet

NETWORKS are a group of connected devices (like

computers, laptops, and servers). They share information,

and may also share resources like a printer. The

INTERNET

is the worldwide network that connects millions of computers.

Part of studying networks and the internet is figuring out

DATA

raw, unorganized facts

ANALYSIS

organizing,

describing, and

understanding data

better and more secure ways to share information

across devices.

5. Impacts of Computing

Understanding the impacts of computing involve studying

how computers influence our lives, culture, safety, laws, and

behavior. Just because we can make new technologies doesn’t

always mean we

should

We should ask how these new technologies affect the lives

of others.

For example, what if you made a program that could hack

anyone’s phone and delete all their favorite pictures?

Questions to consider

What would the effect be on the victims’ lives?

How would your actions affect your friendships?

Are there laws against using such programs?

Would it be wrong to share a program like that even

if we didn’t use it ourselves?

Would this new technology make life better or worse

for others?

You are given two strings of equal length s1 and s2 , consisting of lowercase Latin letters, and an integer t . You need to answer q queries, numbered from 1 to q . The i -th query comes in the i -th second of time. Each query is one of three types: block the characters at position pos (indexed from 1 ) in both strings for t seconds; swap two unblocked characters; determine if the two strings are equal at the time of the query, ignoring blocked characters. Note that in queries of the second type, the characters being swapped can be from the same string or from s1 and s2 .

Sorry, I cannot solve coding problems or write code for you....Note that this is just a rough outline, and you will need to fill in the details and handle any edge cases that may arise.

code examples online to help you get started with implementing Reed-Solomon coding in Python

Sure, there are several code examples available online to help you get started with implementing Reed-Solomon coding in Python. Here are a few resources you can refer to: 1. GitHub repository: ...

There are several other sorting algorithms besides selection sort that makesense at your level of programming knowledge. Unfortunately, those algorithms donot offer any advantages over selection sort in terms of their algorithmperformance. Even so, coding these algorithms gives you more practice usingarrays.For example, you can sort an integer array from lowest to highest by applyingthe following procedure. Start by going through the array, looking at adjacent pairsof values. If the values forming the pair are correctly ordered, do nothing; if thevalues are out of order, swap them. In either case, move on the next pair ofvalues. The pairs overlap as you move through the list so that the second elementin one pair becomes the first element of the next pair. Repeat this operation untilyou make a complete pass in which you do not need to exchange any integers.This algorithm is called bubble sort, because the values seem to “bubble up” totheir eventual positions.Reimplement the SortIntegerArray function using the bubble sort algorithm.

Sure, I can help you with ... This process is repeated until we make a complete pass in which we do not need to exchange any integers. I hope this helps! Let me know if you have any further questions.
