sir plz give an example how both they are working
Sir idont get use of operator== and hashfxn in this video
Hello Devwrath, when we use custom data type for key(such as user defined class etc),
we have to define functions to check equality of key(using == operator overloading) and also a hashfunction so that a valid index is generated.
Both of them are necessary because:
- == operator tells the hashmap whether key used is already there, or is it a new entry.
- hashfunction generates a valid integer value (index) from given key, this index is then used to decide where the given key-value pair be stored in hashtable.
Plz Make me understand dry run of this I am not getting that
What exactly you are unable to understand?
need of these these extra functions or how they are implemented?
if its about need, then go through my previous reply, if it’s about implementation then tell me I will provide you with code for it.
Sir I want to know how they work
see it the code is commented
