Creating a program from flowchart
The document provides steps to create a simple program to check if a number is a multiple of 3:
1. Create a flowchart to plan the program logic and identify necessary variables and conditions.
2. Write JavaScript code that prompts the user for a number, uses the remainder operator to check if it is evenly divisible by 3, and outputs "yes" or "no" accordingly.
3. Use parseInt to convert the input to an integer, and document.write to display the output.
Introduction to flowchart
Flowcharts are used to represent algorithms and processes using graphical symbols. They contain symbols that represent actions, decisions, or connections between steps. The key flowchart structures are sequence, selection, and repetition. Sequence shows steps executed in order. Selection, or decision, determines which steps occur based on a condition being true or false. Repetition allows steps to be repeated as long as a condition is met. These basic structures can be combined to model complex processes and algorithms.

Requirements for software development
Requirements provide a description of what a proposed software application should do. Without detailed requirements, application development projects fail. Business models capture this detail in a way that is understandable to both the business users and the software developers. Business users do not need to understand how the system will be created; they need to understand how it will support their need. Business models are a better form of requirements for end users.

Lesson 4 maya 3
This document discusses working with JavaScript and variables. It provides:
1) An overview of how JavaScript code is placed in HTML and how comments are written.
2) An analogy that variables are like boxes that store content, with the variable name on the box and the stored data as the content.
3) Rules for naming variables in JavaScript, including that names are case sensitive, must begin with a letter or underscore, and keywords cannot be used. Meaningful names are recommended.
Loops
A function is a reusable block of code that can be called anywhere in a program to perform a specific task. This avoids writing duplicate code. The example shows a function called sayHello() that displays an alert box with the text "Hello World". When the button is clicked, it calls this function. The for loop repeats a block of code a specified number of times. The example prompts the user to enter a number and uses a for loop to write "hello" to the page repeatedly if the number is over 200.

Programming Fundamentals
For most programming/scripting languages the concepts are all the same. The only thing that changes is the syntax in which it is written. Some languages may be easier to remember than others, but if you follow the basic guide line, it will make learning any programming language easier. This is in no way supposed to teach you everything about programming, just a general knowledge so when you do program you will understand what you are doing a little bit better.
Web programming
JavaScript is a programming language used to make web pages interactive. It can be placed in the <body> and <head> sections of an HTML page. JavaScript code must be inserted between <script> and </script> tags. Functions and events allow JavaScript code to run when events occur, like when a user clicks a button. Scripts can also be placed in external .js files for reuse across pages. JavaScript can output data through alerts, writing to the HTML, or the browser console. Variables are used to store and work with data in JavaScript programs. Comments are used to explain code and prevent execution when needed.

This assignment will give you practice in manipulating lists of data stored in arrays.
1 General Instructions
Read the general instructions on preparing and submitting assignments.
Read the Counting Words problem description below. Implement the histogram function to
complete the desired program.
You must use dynamically allocated arrays for this purpose.
For your initial implementation, use ordered insertion to keep the words in order and ordered
sequential search when looking for words. Note that the array utility functions from the lecture
notes are available to you as art of the provided code.
Although we are counting words in this program, the general pattern of counting occurrences of
things is a common analysis step in laboratory work, statistical studies, and business tasks. The
results of such a program are often fed into other programs for further processing and/or display.
Such results are often displayed as histograms. The CSV output format is a common “data
exchange” format recognized by many programs. Almost all spreadsheets, for example, will read
CSV files.
When you have the program running, execute it using a short paragraph of text as an input,
saving the output in a file ending with a “.csv” extension. Run a spreadsheet program (e.g.,
Microsoft Excel). You should be able to load your .csv file directly into the spreadsheet.
Try displaying your results as a histogram. In Excel (2007), for example, select the two columns
of data, choose “Sort” from the Data tab and sort your data on the numeric column. Then, with
the two sorted columns of data still selected, go to the Insert tab and select a 2D Bar chart. Save
your spreadsheet in Excel (.xsl) format. You will turn this in later.
As documents get larger, the total number of words increases far, far faster than does the number
of distinct words. Our personal vocabularies are only so large, after all. In fact, most writers
unconsciously limit themselves to writing with a small fraction of their personal “reading”
vocabularies. So most words in a large document are bound to be repeats. That means that, for
this application, the speed of the functions for searching for words is probably more important
than the speed of the functions for inserting new words into the array. We do many more
searches than insertions.
Try running your program on one of the large text files provided in the assignment directory.
Time it to see how long it takes. Now replace all uses of ordered sequential search by calls to the
binary search function. Run it on the same output, timing it again. You should see a substantial
improvement.
Use the button below to submit your completed program and your saved spreadsheet.
2 Problem Description
2.1 Counting Words
Develop a program to prepare a list of all words occurring in a plain-text document, counting
how many times each word occurs. In determining whether two words are different, punctuation
(non-alphabetic.
Introduction to programming c and data-structures
C is a general-purpose programming language developed in the 1970s and closely associated with UNIX. It is widely used due to its portability, standard library concepts, powerful operators, and ability to access hardware. The document provides an introduction to C programming and data structures, covering topics like variables, data types, operators, expressions, and common data structures like arrays, stacks, queues, linked lists, trees, and graphs.

Each group member will create their own slide and confidently present on it for 2-4 minutes, using 1-4 images but no videos. Slides must be free of spelling errors. The group with the best presentation will win a prize, and students have two weeks to complete the project.
Tourism
This document outlines an assignment to build an 8-page tourism website about Bangkok over the next few weeks, including pages about the city's attractions, activities, accommodations, shopping, museums, temples, gardens, and contact information, and instructs to copy source code to help with the project.
Practice programs
The document contains instructions to copy and fix 6 JavaScript programs in Dreamweaver. Each program accepts user input, performs basic operations on the input like substring, length, and division, and writes the output to the document. The programs need to be fixed by completing the blank fields with proper JavaScript syntax like prompt(), name.length, and / to make them work correctly.
Debugging
Debugging a program involves fixing errors to make a program work properly. Common errors include missing quotation marks, missing semicolons at the end of statements, variables without names, and spelling mistakes. The document provides examples of code with various bugs like typing errors, missing elements, and logical errors to demonstrate issues that may occur and need to be fixed through debugging.
Strings
This document discusses JavaScript strings and some of the methods that can be used to manipulate them. Strings can be used to store and manipulate text. Some string methods include substring to return a character at a specific position, toUpperCase and toLowerCase to convert case, indexOf to find the position of a character, and length to determine the number of characters. Examples are provided using prompt and write to demonstrate these string methods.
Loops
A function is a reusable block of code that can be called anywhere in a program to perform a specific task. This prevents having to rewrite the same code multiple times. The document provides an example function called sayHello() that displays an alert box with the text "Hello World" when clicked. It also explains that a for loop repeats a block of code a specified number of times, with the example looping and writing "hello" to the page the number of times dictated by the parameters.
If conditions
JavaScript supports conditional statements like if, if/else, and if/else if statements to perform different actions based on different conditions. The if statement executes code if a condition is true, the if/else statement executes one block of code if the condition is true and another block if false, and the if/else if statement checks multiple conditions in sequence.
Keywords used in javascript
The document discusses keywords used in JavaScript including prompt, parseInt, document.write, and alert. It provides examples of code using these keywords to calculate the perimeter of a square and multiply a user-input number by 20. The keywords need to be filled in the code snippets to make the programs work.
Variables
Variables allow programs to store and manipulate data. There are three main data types: strings, numbers, and booleans. Strings are text surrounded by quotation marks, numbers are used for equations, and booleans are used for true/false conditions. Variables can perform basic math operations like addition, subtraction, and division, and the results can be displayed with alerts. Programs can be written to output a specific number or show an equation followed by the answer in two separate alerts.
Basics
This document provides instructions for coding basic Javascript commands. It explains that Javascript code must be placed within <script> </script> tags, and recommends using Dreamweaver as a code editor for its color-coding features. It then demonstrates how to create an alert pop-up with "hello, world" by adding a <script> tag with an Alert command to an HTML file. Finally, it shows how to save Javascript code into its own .js file and link it within an HTML document using <script src="filename.js"></script>.
Developing html skills 1
The document provides instructions to fix errors in a code sample for a basic website about fruits, including changing the background color, centering the title, modifying font size/color/style, resizing images, and adding hyperlinks. The code sample displays the title "fruits" in large white text on a dark blue background, lists common fruits like banana and apple with an image of a banana, and needs corrections to formatting and functionality.
Matching game
The document lists characteristics of different network topologies and asks the reader to match them to the correct topology. It describes topologies where if one computer or the backbone cable breaks the entire network goes down. It also describes the cheapest and easiest to create but slowest topology, and the most expensive to install but most secure topology where all computers share the same cable. The bonus round describes additional topology characteristics like being the most expensive to create but allowing easy expansion and error detection, relying on the main bus cable so the whole network is crippled if it breaks, withstanding high traffic by transmitting data simultaneously, and being difficult to set up and maintain.
activity flowcharts
The document provides instructions for creating a flowchart to calculate total marks from two tests. It involves inputting the marks from test 1 and test 2, processing them by adding marks1 and marks2 together, and outputting the result.

Mutation Testing for Task-Oriented Chatbots
Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

Essentials of Automations: Exploring Attributes & Automation Parameters
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.
