Solution
The purpose of the map() function in Python is to apply a function to each item in an iterable. This function takes in two arguments: a function and an iterable, and returns a map object with the results. This map object can then be converted into a list or another iterable for use in your program.

How does the map() function work in Python?It filters each element in an iterable based on a condition.It applies a given function to each item of an iterable and returns a list of the results.It reduces an iterable's elements to a single value using a specified function.It iterates through an iterable and stops when the specified function returns False.
unordered_map is an associated container that stores elements formed by the combination of a key value and a mapped value. The key value is used to uniquely identify the element and the mapped value is the content associated with the key. Both key and value can be of any type predefined or user-defined. In simple terms, an unordered_map is like a data structure of dictionary type that stores elements in itself. It contains successive pairs (key, value), which allows fast retrieval of an individual element based on its unique key.Internally unordered_map is implemented using Hash Table, the key provided to map is hashed into indices of a hash table which is why the performance of data structure depends on the hash function a lot but on average, the cost of search, insert, and delete from the hash table is O(1).
