The helper function 'a' has a non-descriptive single-letter name that makes the code difficult to understand. This appears to be implementing searchValue functionality but should have a meaningful name like 'search_value_for_test' or similar to clarify its purpose in the test suite.

[Copilot]

The function parameter names 'b' and 'c' are non-descriptive single-letter names. Consider using meaningful names like 'value' for the parameter being searched and 'current' for the traversal variable to improve code readability.
