Minor fix in the merge_sort comments#38432
Merged
Conversation
There was an off-by-one error discovered by @tbelaire. So, the two invariants we are enforcing are: 1. Run lengths are decreasing. 2. Sum of lengths of any two adjacent runs is less than the length of their predecessor. This commit changes the comment to be clearer and have correct bounds on `i`.

Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @bluss (or someone else) soon. If any changes to this PR are deemed necessary, please add them as extra commits. This ensures that the reviewer can see what has changed since they last reviewed the code. Due to the way GitHub handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed. Large or tricky changes may require several passes of review and changes. Please see the contribution instructions for more information. |
