#### Explanation 1. The function `move` takes a string `x` as input and returns a list of all possible alternate strings. 2. It generates all possible substrings of the input string using nested loops. 3. For each substring, it generates all possible positions to move the substring to. 4. It removes the substring from the original string and inserts it at the new position. 5. The resulting strings are added to a set to eliminate duplicates. 6. Finally, the function returns the list of all possible alternate strings. #### Note * The number of possible alternate strings can be very large for long input strings. * The function may take a significant amount of time to run for long input strings. * The function returns a list of all possible alternate strings, but it does not guarantee that the list is in any particular order.

assert answer == expected, f'Wrong answer; got {answer} instead of {expected}'
print('All tests passed')
And got the output: ['bac', 'abc', 'acb', 'bca', 'cab'] All tests passed

Substring Evaluation

Testing if the previous output contains the string All tests passed: True
