+To implement this program, we will follow a structured approach. We will create a Python script that takes command-line arguments for the inputs, parses them, and then processes each query to determine the minimum number of blows required to defeat Zmei Gorynich. The program will consist of a main function that handles input parsing and output formatting, and a separate function that calculates the minimum number of blows for each query.
+
+We will need to:
+1. Parse the command-line arguments to extract the queries.
+2. For each query, calculate the minimum number of blows required.
+3. Print the result for each query.
+
+Let's start by creating the `main.py` file with the necessary imports and the skeleton of our program.

+To implement the requested functionality, we'll create a Python program that processes the input, evaluates the service history of a car, and outputs the appropriate message based on the criteria provided. We'll structure the program into several parts:
+
+1. **Parsing Input**: A function to parse the input string into a structured format.
+2. **Service History Evaluation**: A class to evaluate the service history entries and determine the status of the odometer and service frequency.
+3. **Main Logic**: The main logic that ties everything together and outputs the final result.
