Explanation of Solution
Linked list:
- Linked List is a data structure which is used to collect a sequence of objects which will allows the efficient access of elements such as adding and removing of elements even from the middle of the sequence.
- It contains numbers of nodes where each node will have a reference to the next.
- To access the elements present inside the linked list the list iterator can be utilized.
Iterator:
Iterators are used to access the elements present inside the linked list.
Output of the code:
The code will print the following:
Diana
Harry
Explanation:
The iterator build the list in the following order “(Tom
, Diana
, Harry
)”, then the first element “Tom
”
gets removed and in the same way the while the loop will print the rest.
At the iteration 1, it prints “Diana” and the staff list will contains “staff = ["Diana", |"Harry"]”.
At the iteration 2, it prints “Harry” and the staff list will contains “staff = ["Diana","Harry"|]”.
In the notations described below the list is enclosed by [
and ] for linked list
, and the iterator is indicated by a |.
Step 1:
The value “Tom” is added to the list “staff”:
iterator...
