Data structures

A data structure is a particular way storing and organizing data in a computer for efficient access and modification. Data structures are designed for a specific purpose. Examples include arrays, linked lists, and classes.

Data Structures is about how data can be stored in different structures. Algorithms is about how to solve different problems, often by searching through and manipulating data structures. Theory about Data Structures and Algorithms (DSA) helps us to use large amounts of data to solve problems efficiently.

A node’s link to the next node is null when there are no nodes to traverse. Plus an example "An ice cream shop that sells three flavors: strawberry, vanilla, and coconut. The signature sundae is made of these three flavors, but new hires have a hard time remembering the order."

For all of the following problems, when it is stated “in the user level” you should assume that you only have the object code of the data structure along with the interface given in the header file. On the other hand, When it is stated that “in the implementation level” you should assume that you have the source code file of the data structure and you should write the desired piece of code within that source code file.
