the interviewer essentially wants to hear about a simplistic O(1) way.

my answer was to store the length of allocated memory in first 4 bytes and return the 4th byte whenever allocating.

while deallocating a previously void * ; go back 4 bytes, read its length and free up length+4 bytes. this will make deallocation a constant time operation.
