The concept is to use some type of function that would allow quickly computing an index in a smaller array to store and looking up the element. Ideally the function would be uniform. That reduces collisions (multiple objects go into the same entry). A way to deal with that is to implement an overflow mechanism allowing multiple buckets Continue reading “Hash Table”
