Perl Weekly Challenge 130: Odd Number and Binary Search Tree
This does more allocations and deallocations, potentially many more, so it will be slower in a lot of cases – in most, I’d even say. The memory savings will only be significant if the list of integers is very large and the mean count of occurrences is very small – and even in that case it depends on the mean distance of occurrences being small, otherwise lots of keys will be kept around at any given time anyway.
