from high level and with a very few collisions, it's O(1). there isn't much to prove because this is based on a common sense.
for example, have the world as a hashtable and all countries as the keys of it. boxes(storage) marked by different country names(key) and you know where to locate them. now, you are given a mail and asked to put it into the box which goes to its destination country. so how many operations does it take you to put a mail in the box? 1 if you realized the mail wasn't misplaced and you need to take it out, how many operations does it take you to take the mail out of the box? i hope this helps a bit -- You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
