fix:bucket count type (#15063)

* fix:bucket count type

* fixed TypeError

* Refine docstring and adjust return statement

Updated docstring for partition_liked_list method to clarify behavior. Changed return statement from None to None for consistency.

* Add script to map open PRs to modified files

This script lists all open pull requests in the current directory's git repository and maps each file touched by any open PR to its corresponding PR numbers. It outputs the results in GitHub-flavored Markdown format.

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Add noqa comments for subprocess calls

Add noqa comments to suppress specific linting warnings.
