Answer:
Step-by-step explanation:
# Pseudocode for gate control based on user input
# Ask the user to enter a number
user_input = input("Please enter a number: ")
# Convert the user input to an integer
try:
number = int(user_input)
except ValueError:
print("Invalid input. Please enter a valid number.")
exit()
# Check if the number is between 0 and 10
if 0 <= number <= 10:
print("Opening Gate 1")
elif 10 < number < 21:
print("Opening Gate 2")
else:
print("Gate 3 is not operational. Please try again later.")
