What is a Data Structure? We knowingly or unknowingly use data structures in our day-to-day life. We form a Queue to board public transport. We will arrange the books on a shelf in a particular order like A-Z, by the height of the books. We...
They can be grown & pruned. What is Linked List? Linked List is a non-contiguous data structure. The singly linked list is a linear data structure in which each list element contains a pointer that points to the next element in the list. Each eleme...

They are everywhere. What is a Tree? Trees are non-linear data structures that are quite often used to represent hierarchical data with a set of connected nodes. Example: The above example student has a set of hierarchical data such as Name, Addres...
