The Correct Answer and Explanation is :

To delete a country from the input string like “Prussia” and handle the necessary output, we would perform the following steps:

Steps for the solution:

1. Input Parsing: The given input string consists of country-capital pairs separated by commas, with each pair in the format “Country:Capital”.
2. Processing the Input:

• Split the string by commas to break down the input into a list of country-capital pairs.
• Iterate over this list and check if any pair corresponds to “Prussia”. If so, remove that pair from the list.

1. Generating Output:

• For each country-capital pair, check if it was removed. If it was, output “Prussia deleted? Yes.”. If it was not, output “Country deleted? No.” for all other countries.

Example Input:

Input: 'Spain:Madrid,Togo:Lome,Prussia:Konigsberg'

Processing:

• The input string can be split into a list: ['Spain:Madrid', 'Togo:Lome', 'Prussia:Konigsberg'].
• We need to check if “Prussia” is in the list and remove it.

Code for Deletion:

def delete_country(input_string, country_to_delete):
    # Split the input string into country-capital pairs
    country_capital_pairs = input_string.split(',')

    # Initialize the result list and a flag for deletion check
    updated_pairs = []
    prussia_deleted = False

    for pair in country_capital_pairs:
        country, capital = pair.split(':')
        if country == country_to_delete:
            prussia_deleted = True
        else:
            updated_pairs.append(pair)

    # Rejoin the pairs to form the new string
    updated_input_string = ','.join(updated_pairs)

    # Return the appropriate response for each country
    output = []
    for pair in country_capital_pairs:
        country, _ = pair.split(':')
        if country == "Prussia":
            output.append(f"Prussia deleted? {'Yes' if prussia_deleted else 'No'}")
        else:
            output.append(f"{country} deleted? {'Yes' if country == country_to_delete else 'No'}")

    return updated_input_string, '\n'.join(output)

input_str = 'Spain:Madrid,Togo:Lome,Prussia:Konigsberg'
updated_input, deletion_report = delete_country(input_str, "Prussia")
print(updated_input)
print(deletion_report)

Explanation:

• Splitting the Input: The string Spain:Madrid,Togo:Lome,Prussia:Konigsberg is split by commas into ['Spain:Madrid', 'Togo:Lome', 'Prussia:Konigsberg'].
• Removing “Prussia”: We check each element in the list. If the country is “Prussia”, we skip it. In this case, “Prussia” is removed, resulting in ['Spain:Madrid', 'Togo:Lome'].
• Building the Output: We generate the output for each country to indicate whether it was deleted or not.

Sample Output:

Spain:Madrid,Togo:Lome
Prussia deleted? Yes
Spain deleted? No
Togo deleted? No
