• Polymorphism allows objects of different classes to be treated as objects of a common superclass, enabling ...read more

Types of search include linear search, binary search, and hash table search. They are used in real life for finding information efficiently.

• Linear search: sequentially checks each element in a list until a match is found.

• Binary search: divides a sorted array in half to quickly find the target value.

• Hash table search: uses a hash function to map keys to values for fast retrieval.

• Real life example: Using linear search to...read more
