Answer:
def sum_digits(number):
total = 0
if 1 <= number <= 999:
while number > 0:
r = int (number % 10)
total +=r
number /= 10
else:
return -1
return total
print(sum_digits(658))
Explanation:
Write a function named sum_digits that takes one parameter, number
Check if the number is between 1 and 999. If it is, create a while loop that iterates until number is greater than 0. Get the last digit of the number using mudulo and add it to the total. Then, divide the number by 10 to move to the next digit. This process will continue until the number is equal to 0.
If the number is not in the given range, return -1, indicating invalid range.
Call the function and print the result
Answer and explanation :
the three control problems associated with competing process are
- MUTUAL EXCLUSION : We know that some resources are shareable and some are not shareable. which means only one process can access the resource at a time this type of resources are called critical resources this code can be access at only one process at a time. the other process if required to access should not be allowed
- DEADLOCK: this hold the process without complete for example suppose there are two resources R1 and R2 and two process P1 and P2 and P1 use R1 and P2 use R2 but after some time when P1 needs R2 but R2 is not available as it is used by P2 so the all process will be on hold
- STARVATION : when priorities are given to the process as high priorities and low priorities. And high priorities process always competing then low priorities process have to wait for very long time this is called starvation
Answer:
Examples of infrastructure include transportation systems, communication networks, sewage, water, and electric systems. Projects related to infrastructure improvements may be funded publicly, privately, or through public-private partnerships.
USB port. That allows you to plug in devices.
import random
computer_choice = random.choice(["rock", "paper", "scissors"])
user_choice = input("rock, paper, or scissors? ")
if computer_choice == user_choice:
print("It's a draw!")
elif user_choice == "rock" and computer_choice == "scissors":
print("You win!")
elif user_choice == "paper" and computer_choice == "rock":
print("You win!")
elif user_choice == "scissors" and computer_choice == "paper":
print("You win!")
else:
print("The computer wins!")
