Answer:
First we understand what is hash function.A hash function is mostly used in Hashmaps. It maps different keys to a set of values.There may occur a case when we have same key but different values.This case is called collision.So we have to use different collision handling techniques that are open addressing and separate chaining.
A perfect hash function maps key-value pair such that there are no collisions.

2. Inheritance
3. Polymorphism
4. Data hiding/ encapsulation
5. Interfaces.

The inheritance is like the subclass of the object. Data hiding is a stage in oop where the codes or data are hidden from another users.
In the polymorphism stage, the object is given the ability to change to a sub-object, while in the interface stage a function or method signature is defined without implementing it.
