This implementation does the following: 1. If the input string is empty or a single character, it returns an empty set. 2. It uses nested loops to: - Extract all possible substrings from the original string - Remove each substring from its original position - Insert the substring at all possible positions in the remaining string 3. It ensures that: - Only unique strings are returned - The original string is not included in the result - Substring moves are possible between any positions Example output for different inputs:

Time and Space Complexity: - Time Complexity: O(n³), where n is the length of the string - Space Complexity: O(n²) to store the alternate strings Key features: - Handles strings of any length - Returns a set to avoid duplicates - Performs comprehensive substring moves - Easily extensible and readable You can modify the function or add more test cases as needed. The current implementation provides a robust way to generate all possible string variations by moving substrings.

This implementation does the following: 1. If the input string is empty or a single character, return an empty set. 2. Use nested loops to: - Extract every possible substring from the original string - Remove that substring from the original string - Insert the substring at every possible position in the remaining string 3. Key points: - Handles various input scenarios (empty string, single char, repeated chars) - Ensures no duplicate strings are generated (using a set) - Excludes the original string from the result Example outputs: For "abc": - "bac" - "cab" - "acb" - "cba" - "bca" For "abcd": - Many variations like "bacd", "cabd", "abdc", etc. Time Complexity: O(n³), where n is the length of the string Space Complexity: O(n²) You can call the function like this: 
1
2
3
# Generate all possible alternate strings
alternates = move("hello")
print(alternates)
The function returns a set of strings, each representing a different way the original string can be rearranged by moving a substring.

# Run the test function
test_move()
This implementation does the following: 1. The `move` function takes a string `x` as input. 2. It creates a set `results` to store unique variations of the string. 3. It uses nested loops to: - Extract all possible substrings - Remove each substring from the original string - Insert the substring at every possible position in the remaining string 4. Key steps in generating variations: - First loop selects the start of the substring - Second loop selects the end of the substring - Third loop determines the insertion position 5. It adds each new variation to the `results` set. 6. The original string is removed from the results to avoid duplicates. Example outputs: For input "abc": 
1
2
3
4
Possible variations:
bca
cab
acb
For input "hello": 
1
2
3
4
5
Possible variations:
elloh
llohe
ohell
...and many more
Time Complexity: O(n³), where n is the length of the input string - First two nested loops: O(n²) to generate substrings - Third loop to insert: O(n) Space Complexity: O(n³) to store all possible variations Some additional notes: - Works with empty strings - Handles single-character strings - Returns a set to ensure unique variations - Excludes the original string from results You can modify the function to return a list instead of a set if you prefer, or add additional constraints as needed. Would you like me to elaborate on any part of the implementation or explain the algorithm in more detail?

This implementation does the following: 1. If the input string is empty or has only one character, return an empty set. 2. Create an empty set to store unique generated strings. 3. Use nested loops to: - Extract all possible substrings from the original string - Remove the substring from its original position - Insert the substring at every possible position in the remaining string 4. Add each new generated string to the results set, ensuring it's different from the original string. 5. Return the set of alternative strings. Example outputs: For "abc":

-----------------
Key points: - Time complexity is O(n³), where n is the length of the string - Returns a set to avoid duplicate strings - Handles various input string scenarios The function generates all possible ways to move a substring to a different position, providing a comprehensive set of alternate string arrangements. You can modify the implementation or add more specific constraints if needed. Would you like me to elaborate on any part of the implementation or explain the logic in more detail?

You can modify the function to return a list instead of a set if you prefer, or add additional constraints as needed. Variations/Improvements you might consider: 1. Add a maximum length constraint 2. Filter variations based on specific criteria 3. Optimize for very long strings 4. Add an option to include/exclude the original string Would you like me to elaborate on any part of the implementation or discuss potential optimizations?
