A) Implement an algorithm to find the shortest path from the start node to the end node using an A* (A-star) heuristic search. Use the straight-line distance to the end node as a heuristic function. Show your pseudo code for this algorithm. Is this an admissible heuristic function? Why or why not?

Hint: Define the necessary functions to implement the search problem. This should include a function that takes a vertex as input and returns the set of vertices that can be reached in a straight line from the given vertex. You may need to implement a function that detects whether two-line segments intersect (the algorithm is attached). The problem can be solved using shortest path algorithms, but you are required to use A*.

B) Present the solutions for the following pair of starting point and ending point using the A* algorithm you implemented. Show the optimal path.

Start: (115, 655) End: (380, 560)

A person who is employed either has a job or is engaged in something. Some individuals think that teenagers with employment are less likely to get into trouble than those without work.

The majority of persons who are working hold traditional full-time occupations, however an increasing proportion also work as independent contractors or in part-time jobs. This adverb can also be used to denote "used," as in the sentence "The used tactics for maintaining the classroom's quiet seem a touch extreme to me."

Because they are created in memory when the function begins execution and destroyed when the function ends, thus local variables will lose their values between calls in the function in which they are already defined.

What is a Variable in the programming?

Variables are names given to locations in the computer memory, where data can be stored in a program. Based on the values assigned to the variables, this data can be known or unknown.

Variables can also be thought of as 'containers,' as they can hold more than one value. Their sole purpose is to store data and label it in memory, which can then be accessed throughout the program as needed.

In C programming, creating variables is also known as declaring variables. Variables are created in a variety of ways depending on the programming language.

Security breaches can have a number of implications for technology adoption.

What is Security breach?
Any incident that results in unauthorised access to data, applications, services, networks, and/or devices by circumventing their underlying security mechanisms is considered a security breach. A security breach occurs when an unauthorised individual or application enters a private, confidential, or unauthorised logical IT perimeter. A security violation is another term for a security breach. A security breach is one of the first stages of a malicious intruder's security attack, such as a hacker, cracker, or malicious application. When the security policy, procedures, and/or system are violated, security breaches occur. A security breach can range from low-risk to highly critical, depending on the nature of the incident.

One of the most direct implications is that people may become hesitant to use the Internet or wireless technology for purchases due to security concerns. If people are worried that their personal information may be compromised in a security breach, they may be less likely to use online or mobile platforms for shopping or banking. Additionally, people may be hesitant to use technology because of privacy concerns. If people are worried that their data may be accessed or used without their consent, they may be less likely to use certain technologies. These concerns may be warranted, and they may be influenced by age, race, or gender.

The various windows in IDA Pro are used for different purposes. The main window is used for displaying the disassembly of the program.

What is program?
A computer utilises a set of instructions called a program to carry out a particular task. A program is like the recipe for a computer, to use an analogy. It includes a list of components (called variables, which can stand for text, graphics, or numeric data) and a list of instructions (called statements), which instruct the computer on how to carry out a certain activity. Specific programming languages, such C++, Python, and Ruby, are used to construct program. These are high level, writable, and readable programming languages. The computer system's compilers, interpreters, or assemblers subsequently convert these languages into low level machine languages. Technically, a human could write assembly language, a kind of low level language that really is one step above machine language. The register window is used for displaying the values of the registers. The memory window is used for displaying the contents of the memory. The cross-reference window is used for displaying the data and code cross-references. The data and code cross-references are used for finding the locations of the data and code that are referenced by the program.

A deadlock cannot occur because each process only needs a maximum of two resource units, and there are four resource units that can be reserved and released one at a time.

What is deadlock?
Any circumstance in which no member of a group of entities can move forward because each one is waiting for another member, including itself, to act, such as sending a message or, more frequently, releasing a lock, is referred to as a deadlock in concurrent computing. Due to the frequent usage of hardware or software locks in multiprocessing, parallel computing, or distributed systems to manage shared resources to implement process synchronisation, deadlocks are a typical issue in these environments. When a process or thread enters a waiting state due to a system resource being held by some other process that also is waiting for another resource which is being held by some other waiting process, a deadlock occurs in the operating system.

What is code?
For the purposes of communication and information processing, a code is a set of principles that transforms information—such as a letter, word, sound, picture, and gesture—into another form, sometimes shorter or secret, for storage on a storage device or for transmission over a communication channel. An early example is the development of language, which allowed people to express verbally what they were thinking, seeing, hearing, or feeling to others. However, speaking restricts the audience to those present at the time the speech is delivered and limits the range of communication to a distance a voice may travel. The ability to communicate across time and space was greatly expanded by the discovery of writing, which transformed spoken words into pictorial symbols. Encoding is the process of transforming data from a source to symbols for transmission or storage.

Unrestrained steel beams are those that have a compression flange that can rotate and move (or displace) freely.
