So, What is the differnece between Array & Set ? When to use Set? When to use Array ?

[@LearnWithKarl]

Hey Rashesh, Choose the Array is you need an ordered sequence of non-unique elements, e.g. [1, 5, 5, 7, 7, 14, 1]. Whereas if you need *unique* values, and *their order doesn't matter*, use a Set. Also, the set has various useful operations like union, intersect, difference etc.

can you give me a real time example for Hashable?

[@LearnWithKarl]

A type needs to conform to Hashable if you want to use its instances in a Set or as Dictionary keys. The video shows you an actual example.
