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)
What is the explanation for the above program?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.

A list is sorted in ascending order if it is empty or each item except the last one is less than or equal to its successor. Define a predicate isSorted that expects a list as an argument and returns True if the list is sorted, or returns False otherwise.
(Hint: For a list of length 2 or greater, loop through the list and compare pairs of items, from left to right, and return False if the first item in a pair is greater.)
Below is an example of a main function and the associated output:
def main():
lyst = []
print(isSorted(lyst))
lyst = [1]
print(isSorted(lyst))
lyst = list(range(10))
print(isSorted(lyst))
lyst[9] = 3
print(isSorted(lyst))
True
True
True
False
The isSorted is a predicate that expects a list as an argument and returns True if the list is sorted, or returns False otherwise.
Here's the implementation of the isSorted predicate in Python:
def isSorted(lyst):
if len(lyst) <= 1:
return True
else:
for i in range(len(lyst)-1):
if lyst[i] > lyst[i+1]:
return False
return True
The isSorted predicate first checks if the list is empty or contains only one element, in which case it is already sorted and the function returns True. Otherwise, it loops through the list and compares each pair of adjacent items. If any item is greater than its successor, the function returns False. If the loop completes without finding any out-of-order pair, the function returns True.
The main function creates some test cases by defining different lists and calling the isSorted predicate on them. The expected output for these test cases is shown in the comments:
def main():
lyst = []
print(isSorted(lyst)) # True
lyst = [1]
print(isSorted(lyst)) # True
lyst = list(range(10))
print(isSorted(lyst)) # True
lyst[9] = 3

Discuss fitness for purpose (Suitability of the material/s). (2) 2.3. Explain the safety of the bridge for the users. (2) 2.4. Investigate the cost of materials needed to build a bridge. You are expected to give realistic examples of some building materials. You may need to ask other people or visit hardware. You can write the price per unit of the materials. (4) 2.5. Write down the costs of labor for both skilled and unskilled labor per hour. Calculate the total per month. (4)
Answer:
Explanation:
2.1. The two main materials commonly used to construct a bridge are steel and concrete. Steel is used for constructing the main support structure of the bridge, while concrete is used for the decking and other components.
2.2. Both steel and concrete are considered suitable materials for bridge construction. Steel is known for its strength and durability, while concrete offers good compression strength and can resist harsh environmental conditions. Steel is also flexible and can be used to construct complex shapes and designs, while concrete can be molded into various shapes and sizes. Both materials are widely available and can be sourced easily.
2.3. The safety of a bridge largely depends on the quality of construction and the maintenance of the structure. If constructed properly with high-quality materials, a steel or concrete bridge can be very safe for users. Steel is known for its ability to resist fatigue and can withstand heavy loads, while concrete is fire-resistant and can provide good impact resistance. Proper maintenance, regular inspections, and repairs can help ensure the safety of the bridge over time.
2.4. The cost of materials needed to build a bridge can vary depending on several factors, such as the length of the bridge, the design, and the location. For example, the cost of steel can range from $500 to $1,500 per ton, while the cost of concrete can range from $100 to $150 per cubic yard. Other building materials such as asphalt and timber can also be used for bridge construction, with prices ranging from $100 to $500 per ton or per cubic meter, respectively.
2.5. The cost of labor for bridge construction can also vary depending on the level of skill required and the location. Skilled labor such as engineers and welders can cost anywhere from $50 to $200 per hour, while unskilled labor such as laborers and construction workers can cost from $10 to $30 per hour. Assuming a 40-hour workweek, the total labor cost for skilled labor can range from $8,000 to $32,000 per month, while the total labor cost for unskilled labor can range from $1,600 to $4,800 per month.

The provided example code indicates that Row-Major order is quicker than Column-Major order.
The order that elements of a two-dimensional array are kept in memory is referred to as row-major. The items of one row are kept together in a row-major order, then the elements of the next row, and so on. This makes it efficient to iterate across each row of the array, accessing its elements one at a time. The array can be traversed more quickly column by column when the components of a column are stored together in column-major order. Programming languages like C and Java frequently employ row-major ordering. It is helpful for operations like matrix multiplication or linear algebra that require iterating through a matrix's rows.

what economic problem can be caused by having ubi programs as optional programs?
Universal Basic Income (UBI) programs can cause economic issues such as inflation, budget deficits, and decreased labor force participation. Inflation occurs because UBI may increase the amount of money in circulation and cause prices to rise. Budget deficits can also occur as UBI is an expensive program to fund.
These issues are discussed in greater detail below: Inflation: UBI is funded by tax revenues, which means that the government must raise taxes to finance the program.
The introduction of a UBI program may lead to an increase in inflation, particularly if the government uses deficit spending to fund the program. This may result in a reduction in the overall workforce, which may have a negative impact on the economy.
A smaller workforce means that there are fewer people contributing to the economy and more people relying on government support. This could lead to a decline in economic growth and a decrease in tax revenues for the government.
The advantages of UBI are evident, but we must be cautious when implementing it as an optional program, as it may have unforeseen economic implications.

Which of the following functions of TCP control the amount of unacknowledged outstanding data segments?
A. Flomax
B. Segmentation
C. Windowing
D. Flow Control
The TCP function that controls the amount of unacknowledged outstanding data segments is D) flow control.
Flow control is a critical function in data communication to prevent data loss and overload in the network. TCP flow control regulates the rate of data transmission, ensuring that the receiving device can manage the data transmission effectively. The following are some of the features of TCP flow control:
Sliding windows are used in flow control. The sender divides data into small segments called TCP segments and transmits them one by one. TCP segments are only sent if the receiving end's buffer can accommodate them. TCP flow control regulates the amount of data that can be transmitted to the receiving end by controlling the amount of unacknowledged data segments at any time. TCP uses the Explicit Congestion Notification (ECN) mechanism to monitor the congestion status of the network and regulate data transmission. Flow control's goal is to prevent network overloading and ensure that data is delivered to the receiver accurately and promptly. Therefore, in conclusion, option D flow control is the correct answer.Learn more about Flow control visit:
