Create a list : The Concat Solution

The video tutorial reviews array lists and linked lists, highlighting their differences in memory structure and efficiency. Array lists offer fast read and write access due to contiguous memory allocation but require shifting elements for insertions and deletions. Linked lists, on the other hand, allow efficient insertions and deletions without shifting but require traversal for access. The tutorial also discusses practical applications, such as in video games, where linked lists can improve performance by handling frequent additions and removals efficiently.

What is a key structural difference between an array list and a linked list?

• Linked lists do not use pointers.

• Array lists store elements in contiguous memory locations.

• Linked lists store elements in contiguous memory locations.

• Array lists use nodes connected by pointers.

What is the time complexity of reading an element from an array list?

• O(1)

• O(log n)

• O(n)

• O(n^2)

Why is inserting an element in an array list considered inefficient?

• It requires shifting all elements.

• It requires sorting the list.

• It requires updating all pointers.

• It requires additional memory allocation.

What is the time complexity of removing a node from a linked list if the node is accessible?

• O(n)

• O(log n)

• O(n^2)

• O(1)

What is a disadvantage of using linked lists compared to array lists?

• Linked lists cannot store complex data types.

• Linked lists have slower read access.

• Linked lists require more memory for pointers.

• Linked lists are not suitable for dynamic data.

In what scenario did the use of a linked list improve performance in a video game?

• When elements were frequently sorted.

• When elements were frequently added and removed.

• When elements were accessed randomly.

• When elements were stored in a fixed order.

What was the main performance issue with using an array list in the video game example?

• The array list could not handle large data sets.

• The array list required frequent shuffling of elements.

• The array list had slow read access.

• The array list required constant sorting.
