Linked List is a dynamic data structure while Arrays are static.

• Linked List can grow or shrink dynamically while Arrays have fixed size.

• Linked List uses pointers to connect nodes while Arrays use indexes to access elements.

• Insertion and deletion are faster in Linked List while accessing elements is faster in Arrays.

• Arrays use contiguous memory while Linked List uses scattered memory.

• Arrays are suitable for small data sets while Linked List is suitable for large data sets.

To insert a node at the last of a single linked list, traverse to the end and point the last node to the new node.

• Traverse the linked list till the last node is reached

• Create a new node with the given data

• Point the next of the last node to the new node

• Make the new node as the last node

Distinct vs Null: unique values vs absence of value. Parallel period vs Same period last year: comparing current vs previous time periods.

• Distinct values are unique values in a dataset, while null represents the absence of a value.

• Parallel period compares data from the same time period in different years, while Same period last year compares data from the previous year.

• For example, if we are comparing sales data for January 2021 to January 2020, it would be a parallel period ...read more
