You need to develop a program that simulates the reception and processing of requests: the program should automatically generate new requests (identified by a unique number or other data), add them to a queue, and then sequentially remove them from the queue for "processing," thus mimicking the operation of a service center.
Here is the pseudocode for the task using a queue (Queue from the queue module in Python) for the request processing system:
import queue
# Create the request queue
request_queue = queue.Queue()
# Function to generate a new request
def generate_request():
# Create a new request
new_request = ...
# Add the request to the queue
request_queue.put(new_request)
# Function to process a request
def process_request():
if not request_queue.empty():
# Remove a request from the queue
request = request_queue.get()
# Process the request
...
else:
print("The queue is empty")
# Main program loop
while user_does_not_exit:
generate_request() # Generate new requests
process_request() # Process requests
In this pseudocode, two main functions are used: generate_request(), which generates new requests and adds them to the queue, and process_request(), which processes requests by removing them from the queue. The main program loop runs these functions, simulating a continuous flow of new requests and their processing.
You need to develop a function that takes a string as an input parameter, adds all its characters to a deque (deque from the collections module in Python), and then compares the characters from both ends of the deque to determine if the string is a palindrome. The program should correctly handle strings with both even and odd numbers of characters, and be case-insensitive and ignore spaces.
In many programming languages, we deal with expressions delineated by separator characters such as round ( ), square [ ], or curly braces { }.
Write a program that reads a string with a sequence of separator characters, such as ( ) { [ ] ( ) ( ) { } } }, and provides an appropriate message when the separators are symmetrical, asymmetrical, such as ( ( ( ), or when separators of different kinds are paired, such as ( }.
💡 Use a stack to keep track of currently open separator characters.
Example of Expected Results: ( ){[ 1 ]( 1 3 )( ){ }}: Symmetrical ( 23 ( 2 - 3);: Asymmetrical ( 11 }: Asymmetrical
