Nice work, take a look at my comments regarding time complexity. Also could you reuse 1 method to do the reverse on individual words?
| return string | ||
| end | ||
|
|
||
| def word_reverse(string) |
| return my_sentence | ||
| end | ||
|
|
||
| def string_reverse(string) |
| # Time complexity: ? | ||
| # Space complexity: ? | ||
| # A method to reverse the words in a sentence, in place. | ||
| # Time complexity: O(n^3) |

This is actually O(n) as a solution.

This does the same logic as reverse_sentence, so why not make the method flexible enough to be used in both places.
