* fix: prevent NPE when array contains null elements

When searching for a non-null key in an array that contains null elements,
the sentinel linear search would throw a NullPointerException because it
called array[i].compareTo(key) without checking if array[i] is null.

Added null check for array[i] in the while loop condition to prevent NPE
and return the correct index when array elements themselves are null.

Issue: TheAlgorithms#7318 (related)
