## How This Works: 1. We consider every possible substring of `x` by iterating through: - All possible lengths (from 1 to the length of the string) - All possible starting positions for each length 2. For each substring: - We extract it from the original string - We create a base string with the substring removed - We insert the substring at every possible position in the base string 3. We only keep results that are different from the original string (otherwise, it's not really "moving" the substring). 4. We use a set to automatically eliminate duplicates before returning the final list. ## Example: For the input "abc", the function would return ["acb", "bac", "bca", "cab"], which represents all possible ways to move a substring of "abc" to another position.

# Understanding the Problem I need to create a function called `move` that: 1. Takes a string `x` as input 2. Returns all possible strings `y'` that can be formed by: - Taking a substring from `x` - Moving that substring to another position in the string - Ensuring the resulting string is different from the original # Solution

# Explanation The function works in three steps: 1. **Identify all possible substrings**: We use two loops to consider every possible substring in the original string. 2. **Remove and reinsert**: For each substring, we remove it from its original position and consider all possible positions to insert it back into the remaining string. 3. **Check validity**: We only keep strings that are different from the original, as reinserting a substring in the same position wouldn't be considered a "move". # Examples Let's trace through a simple example with the string "abc": - Moving substring "a" (from position 0): - Remove "a", remain with "bc" - Insert at positions: "abc" (same as original, ignored), "bac", "bca" - Moving substring "b" (from position 1): - Remove "b", remain with "ac" - Insert at positions: "bac", "abc" (ignored), "acb" - And so on for all possible substrings... For the string "abc", the function would return: ["acb", "bac", "bca", "cab", "cba"]
