To solve this task, you need to implement several functions as mentioned in the code comments. Here's an explanation of each step:

1. Implement a function that parses clients' data into proper containers: This function will take the client data string and parse it into appropriate data structures, such as vectors, arrays, or a custom client object. You'll need to split the string into individual client entries and extract the relevant information (phone number, first name, last name, and age) for each client.

2. Implement a function that finds the youngest client: In this function, you need to iterate through the client data and compare the ages of the clients to find the youngest one. You can store the youngest client's information in variables or a separate data structure to return from the function.

3. Implement a function that sorts the clients by the first name: This function will take the parsed client data and sort it based on the first name of each client. You can use a sorting algorithm like Bubble Sort or any other sorting technique. Make sure to consider the case where multiple clients may have the same first name.

4. Implement a function that prints out the sorted client list: Once the client data is sorted, iterate through the sorted data and print out the information for each client. You can use a loop or any other method to iterate over the sorted data.

5. Call these functions in main following the same mentioning order: In the main function, call each of the implemented functions in the mentioned order to perform the required operations and obtain the desired output.

Remember to declare the functions before using them in the main function, either by adding function prototypes or by rearranging the code to define the functions above the main function.
