Question
(Reverse number) Write a program that prompts the user to enter a four-digit integer and displays the number in reverse order. Here is a sample run:
Enter an integer: 3125
The reversed number is 5213
Answer
Reverse Number Program Code:
# Prompt the user to enter a four-digit integer
number = int(input("Enter an integer: "))
# Extract each digit from the number
digitOne = number % 10
digitTwo = (number // 10) % 10
digitThree = (number // 100) % 10
digitFour = (number // 1000) % 10
# Build the reversed number
reversedNumber = digitOne * 1000 + digitTwo * 100 + digitThree * 10 + digitFour
# Display the reversed number
print("The reversed number is", reversedNumber)
Executed Output 1:
Enter an integer: 3125
The reversed number is 5213
Executed Output 2:
Enter an integer: 1234
The reversed number is 4321
