Queue class is similar to a 'printer queue' where all document is awaiting to be proceed when the current one will be finished.

A common scenario in applications is having a pool of worker threads that has to process several objects waiting in a queue. The operation to be executed on the waiting objects is the same, but it can be carried out by different threads on different objects.

List is similar to a tower where you can put item into.

1st stage = hello
2nd = manavsi
3rd = from
4nd = d1rtyw0rm

And then you can consult the list in order to get the item that you want.

Lists are a kind of sequence containers. As such, their elements are ordered following a linear sequence.

List containers are implemented as doubly-linked lists; Doubly linked lists can store each of the elements they contain in different and unrelated storage locations. The ordering is kept by the association to each element of a link to the element preceding it and a link to the element following it.

This provides the following advantages to list containers:


Efficient insertion and removal of elements anywhere in the container (constant time).
Efficient moving elements and block of elements within the container or even between different containers (constant time).
Iterating over the elements in forward or reverse order (linear time).
