• It can be used to release resources like closing files or sockets.

• It is not recommended to rely on 'finalize' for resource cleanup as it is not guaranteed to be called.

• Another approach is to sort the array and use two pointers, one starting from the beginning and the other from the end, to find the pair.

• If the array is sorted, we can also use binary search to find the complement of each numbe
