### Educational Website Transcription: Understanding Greatest Prefix Function

**Example Function Parameters:**
```plaintext
greatest_prefix("Solar system", "Solar panel!")
```

**Example Function Return Value:**
```plaintext
"Solar "
```

**Example Function Parameters:**
```plaintext
greatest_prefix("ABCCA", "ADCCA")
```

**Example Function Return Value:**
```plaintext
"A"
```

**Example Program Input:**
```plaintext
Solar system
Solar panel!
```

**Example Program Output:**
```plaintext
The largest prefix of 'Solar system' and 'Solar panel!' is 'Solar ' with size 6.
```

**Note:** Be careful with spaces :)

This example demonstrates how the `greatest_prefix` function operates by identifying the longest common prefix in two strings. It is crucial to pay attention to spaces, as they are part of the prefix.

8.17 LAB: Two prefixes

**Learning Objectives**

- Create a function with the required parameters and return value
- Use a for loop to go over !size! of the substring
- Use slicing to get the substring

**Instructions**

A little bit of looking back to strings:

- A substring - any part of a string
- A prefix - part of the string that starts from the very beginning of the initial string.
- Example: string "you are so nice" has prefixes "y", "you", "you ar", "you are so" and that is not all of them!

Create a function `greatest_prefix(..)` that would return the same largest prefixes for two strings.

Create a program that would read two strings, use your function to find the largest prefix for them, and print it and its size in a sentence:
The largest prefix of 'A' and 'B' is 'prefix' with size N.
