C++ // Counting Sort // "Handle empty array" #1460

Closed JeninSutradhar closed 1 month ago

JeninSutradhar commented 1 month ago

Counting Sort C++ C++ implementation is mostly correct but it does not handle the case where the input array is empty.

if (nums == null || nums.length == 0) { return; // handle empty array }

Add a check at the beginning to return immediately if the input array is empty or null.
