Answer:
def countdown(n):
if n <= 0:
print('Blastoff!')
else:
print(n)
countdown(n-1)
def countup(n):
if n >= 0:
print('Blastoff!')
else:
print(n)
countup(n+1)
number = int(input("Enter a number: "))
if number >= 0:
countdown(number)
elif number < 0:
countup(number)
<u>Outputs:</u>
Enter a number: 3
3
2
1
Blastoff!
Enter a number: -3
-3
-2
-1
Blastoff!
Enter a number: 0
Blastoff!
For the input of zero, the countdown function is called.
Explanation:
Copy the countdown function
Create a function called countup that takes one parameter, n. The function counts up from n to 0. It will print the numbers from n to -1 and when it reaches 0, it will print "Blastoff!".
Ask the user to enter a number
Check if the number is greater than or equal to 0. If it is, call the countdown function. Otherwise, call the countup function.
Answer:
Input, Processing, Storage, Output and Communication devices.
Explanation:
Input devices of computer are like Keyboard, Mouse, Scanner. Output devices of a computer are printers, monitors, and headphones.
There are two storages of computer one of them is REM, which can be lost if computer shutdown/closes. Data stays written on the disk until it's erased or until the storage medium fails (more on that later). An example of a communication device is the microphone.
Answer:
John von Neumann is remarkable for his vast knowledge of mathematics, and the sciences as well as his ability to correlate the pure and applied sciences.
Explanation:
John von Neumann who was born on December 28 1903, and died on February 8,1957 was known for his extensive knowledge of mathematics, physics, computer, economics, and statistics. In computing, he was known to conceive the idea of the self-replicating machines that thrive in the automata cellular environment, the von Neumann architecture, stochastic computing and linear programming.
He developed the game theory in Economics, and laid the foundation for several mathematical theories. He contributed greatly to quantum mechanics and quantum physics. Little wonder, he was dubbed "the last representative of the great mathematicians."
