Code -
def long_running_task(n):
num = 0
for x in range(n):
for y in range(n):
for z in range(n):
num += x + y + z
return num
print(long_running_task(500))

Transcribed Image Text:Write a Python decorator function that accepts any function as input, starts a timer, calls the function with a single
argument, and then ends the timer and prints out how long the function took to run. Use the Python time module
to time the accepted function. Decorate the long_running_task function using the Python decorator syntax and
print the results.
$ python main.py
fn took 13.040512561798096s to run

- Data Structure Using C++ (Queue) C++ code (NOT JAVA C++ JUST) C++ PROGRAMMING LANGUAGE PLEASE :: We can use a queue to simulate the flow of customers through a check-out line in a store. In this simulation we will have the following details: one check-out line the expected service time for each customer is one minute (However, they may have to wait in line before being serviced) between zero and two customers join the line every minute We can simulate the flow of customers through the line during a time period n minutes long using the following algorithm: Initialize the queue to empty. for ( minute = 0 ; minute < n ; ++minute ) { if the queue is not empty, then remove the customer at the front of the queue. Compute a random number k between 0 and 3. If k is 1, then add one customer to the line. If k is 2, then add two customers to the line. Otherwise (if k is 0 or 3), do not add any customers to the line. } In addition, the algorithm will keep track…arrow_forwardHaskell Programming: Jeff and Elon are discussing about space how will it increase their business. They are planning to make an international space station, We have N asteroids in the space also there has been N-1 pairs asteroids with Links. Each link has a unique assignment of numbers and since Elon is fond of palindromes he wants that the path chooses is such that it is a palindrome. Print YES if it is possible else NO.
