Aiom for the ADT List. C++ Explain what this pseudocode is doing.

aList.getEntry(i) = (aList.insert(i, item)).getEntry(i+1)

Solution

You have a list

and we know list has index starting from

0, 1,2,3,4,5,6,.....

So

(aList.insert(i, item)): Inserts item at index i
(aList.insert(i, item)).getEntry(i+1) : Inserts item at index i and fetches and returns the element at index i+1

aList.getEntry(i) = (aList.insert(i, item)).getEntry(i+1)

So, it means  (aList.insert(i, item)).getEntry(i+1) Inserts item at index i and fetches and returns the element at index i+1 and assigns it to element at index i.
