Answer 2

Swapping the Whole and Decimal Parts of a Number

To swap the whole and decimal parts of a number of the form nnn.ddd, you can use the following algorithm:

1. Extract the whole and decimal parts of the number. 2. Swap the positions of the whole and decimal parts. 3. Output the new number with the swapped parts.

Here's a simple algorithm to achieve this:

1. Extract the whole and decimal parts of the number. 2. Swap the positions of the whole and decimal parts. 3. Output the new number with the swapped parts.

For example, if the original number is 123.456, after swapping, it becomes 456.123.

Let's implement this algorithm in a programming language like Python:

# Input the number in the format nnn.ddd
number = input("Enter the number in the format nnn.ddd: ")

# Extract the whole and decimal parts
whole_part, decimal_part = number.split('.')

# Swap the positions of the whole and decimal parts
new_number = decimal_part + '.' + whole_part

# Output the new number with the swapped parts
print("The new number after swapping is:", new_number)

You can run this code and input a number in the format nnn.ddd to see the swapped result.

Note: This is a simple algorithm and code example to demonstrate the swapping of whole and decimal parts of a number. The actual implementation may vary based on the programming language and specific requirements.
