Answer:System errors are caused by malfunctioning hardware components, corrupted operating system modules, etc. These are caused by corrupted or malfunctioning system files or software executables. Most runtime errors affect the application that caused it to shut down.

Explanation:

Here is an implementation of a Python program that reads an input grammar from standard input, and a task number from the command line argument, performs the requested task, and prints the results to standard output:

import sys

def task_one(terminals, nonterminals):

   print(' '.join(terminals + nonterminals))

def remove_useless_symbols(grammar):

   reachable = set('S')

   new_reachable = set('S')

   while new_reachable != reachable:

       reachable = new_reachable.copy()

       for lhs, rhs_list in grammar.items():

           if lhs in reachable:

               for rhs in rhs_list:

                   for symbol in rhs.split():

                       if symbol in grammar:

                           new_reachable.add(symbol)

   return {lhs: [rhs for rhs in rhs_list if all(symbol in reachable for symbol in rhs.split())] for lhs, rhs_list in grammar.items()}

def task_two(grammar):

   modified_grammar = remove_useless_symbols(grammar)

   for lhs, rhs_list in modified_grammar.items():

       for rhs in rhs_list:

           print(f"{lhs} -> {'# ' if not rhs else rhs}")

def read_grammar():

   grammar = {}

   for line in sys.stdin:

       lhs, rhs = line.strip().split(' -> ')

       grammar.setdefault(lhs, []).append(rhs)

   return grammar

if __name__ == '__main__':

   task_number = int(sys.argv[1])

   grammar = read_grammar()

   if task_number == 1:

       terminals = sorted(set(symbol for rhs_list in grammar.values() for rhs in rhs_list for symbol in rhs.split() if symbol.islower()))

       nonterminals = sorted(set(grammar.keys()))

       task_one(terminals, nonterminals)

   elif task_number == 2:

       task_two(grammar)

The program defines two functions task_one() and remove_useless_symbols() to perform the two tasks. The task_one() function takes a list of terminals and a list of non-terminals, concatenates them in the order they appear in the grammar rules, and prints the result to standard output. The remove_useless_symbols() function takes a dictionary representing the input grammar, removes any non-reachable or non-productive symbols, and returns a modified grammar in the format specified for task two.

The program also defines a read_grammar() function that reads the input grammar from standard input and returns a dictionary representing the grammar. The main code block reads the task number from the first command line argument, reads the input grammar using read_grammar(), and performs the requested task using the appropriate function. For task one, the program first calculates the list of terminals and non-terminals by iterating over the grammar rules, extracting the symbols using string splitting and filtering for lowercase letters and non-lowercase letters respectively.

Supply Chain strategy is essential in every organization that involves the planning and management of all activities involved in sourcing, procurement, conversion, and logistics. In doing so, the goal is to optimize supply chain networks for average performance.

It is the right approach to optimize supply chain networks for "average" performance because it helps the company attain its objectives and improve its performance. It makes the planning and management of activities in sourcing, procurement, conversion, and logistics more efficient by making use of resources at an optimal level. Also, this approach allows the company to maintain the right balance between supply and demand by producing enough products to meet the customers' demands. By doing so, the company reduces costs, increases efficiency, and enhances customer satisfaction. However, sometimes, optimizing supply chain networks for "average" performance may not be the right approach. This is because customers' preferences are not average. Also, different customers have different needs. Thus, optimizing the supply chain for an average performance level may result in dissatisfied customers who may opt to seek services from the competitors. Thus, it is essential to ensure that the optimization strategy considers the customers' needs and preferences, and a balance is achieved. In conclusion, optimizing the supply chain for average performance is the right approach in most cases. However, this approach should consider the customers' needs and preferences to achieve a balance between supply and demand. Therefore, when locating facilities in a network, transportation economies about the potential facility location should be considered. This means that the facility should be located in an area that is easily accessible to transportation. Additionally, the network should be configured in such a way that the facility is linked to other facilities in the supply chain network to allow for efficient transportation.

public static void main(String[] args) {

    int nPositive = 0;

    int[][] a2d = {{-7,28, 92}, {0,11,-55}, {109, -25, -733}};

 for (int i = 0; i < a2d.length; i++) {

                  for(int j = 0; j < a2d[i].length; j++) {

         if(a2d[i][j] > 0){

             nPositive++;

                       }

                  }

 }

 System.out.println(nPositive);

}

}

Explanation:

*The code is in Java.

Initialize the nPositive as 0

Initialize a two dimensional array called a2d

Create a nested for loop to iterate through the array. If an element is greater than 0, increment the nPositive by 1

When the loop is done, print the nPositive

Answer:

const a2d =  [[7,28, 92], [0,11,-55], [109, -25, -733]];

In the following code snippet, the local variables of the function modByTwo are the result and x. The correct option is a.

A local variable is one that can only be accessed from within a certain section of a program. These variables are often declared or defined within a subroutine and are local to that routine.

Local variables can alternatively be thought of as parameters that have values. The duration of the program's execution is reflected in a global variable. When the function is called, a local variable is created, and it is removed after the function has run its course. All the program's functions have access to it at all times.

One particular sub-program of a bigger main program declares a local variable. The values of local variables will be stored in RAM while this sub-program is running.

Therefore, the correct option is a, result, and x.

The answer is False i.e there is a difference between defining an object of an ordinary class and an object of a template class.

The class of an object, which is an analytical unit, determines both its behavior and contents. In other words, it is a manual or blueprint for creating a specific kind of object. Initial values are provided for member variables, member functions, and member methods.

An object is a self-contained unit that has methods and properties to help make data useful. You can use it to determine how the class will act.

From the standpoint of programming, an object can be a data structure, a variable, or a function that has been given a memory address. The object is designed with a class structure.

A class specifies the properties of an object, such as the acceptable range of values and the default value. Object behavior is also described by a class. A member or "instance" of a class is an object. Every property of an object has a state in which those values are either explicitly declared by you or are determined by default settings.

By itself, template class is not a type, an object, or any other kind of thing. A source file that solely has template definitions is not converted into code.

The given question can be answered by option 'a. Thin client.' A low-cost, centrally managed computer with limited capabilities and no internal or external attached drives for data storage is called a thin client.

What is a thin client?

A thin client, sometimes known as a slim client, is a low-cost, centrally managed computer with limited capabilities and no internal or external attached drives for data storage. Thin clients are used in a client-server architecture to allow for remote access to graphically intensive applications. In other words, thin clients are computers that use a server's processing power to drive the user interface and other computer functions.

What are the benefits of using thin client computers?

Thin clients provide a number of advantages, including the following:Lower costs: Thin clients are less expensive than standard PCs. Because they don't require a lot of processing power, they don't require high-end components. They also don't have internal storage, which can be a significant expense.Reduced Maintenance: Thin clients are much simpler to maintain than standard PCs. They are centrally managed, which means that administrators may deploy updates and software patches to all devices at the same time. Thin clients, unlike standard computers, do not require frequent updates or antivirus software. Because there is no internal hard drive, there is little risk of data loss in the event of a hard drive failure.
