1e6a84119a Update array_hash_map.py (#1803) 
基于数组实现的哈希表中，`get()` 函数的返回值还可能会 None；且 `put()` 函数不仅可添加键值对、还可更新表中已有键值对的值；

7e904c8ff6 Update counting_sort.py (#1677) 
Since the max function is called to find the maximum value, it doesn't seem necessary to traverse the list and call the max function several times to select the larger value.

6a74972080 fix(lang: c, chapters: searching, sorting): Some serious errors (#1531) 
* fix: correct hash table insertion

* Use a pointer to a pointer instead of a single pointer in the insert function, ensuring proper updates to the hash table
* Bug fixes: This fixes issues with empty results.

* fix: correct issues in radix sort

* Replaced loop-based array copy with memcpy to ensure efficient memory copying in countingSortDigit
* Fixed a bug in radixSort where the maximum value search loop skipped the last element
* Bug fix: Ensures all elements are checked when determining the maximum value in the array

* perf: improve memory management by adding explicit memory release

* revert: Revert to using the old loop override array method and drop specific api's like memcpy.
