What is the need of chart in real life?
Charts are often used to ease understanding of large quantities of data and the relationships between parts of the data. Charts can usually be read more quickly than the raw data. Certain types of charts are more useful for presenting a given data set than others.

What is BST give a real life example?
Binary Search Tree – Used in many search applications where data is constantly entering/leaving, such as the map and set objects in many languages’ libraries. Binary Space Partition – Used in almost every 3D video game to determine what objects need to be rendered.
Which is the best data structure?
Arrays. An array is the simplest and most widely used data structure. Other data structures like stacks and queues are derived from arrays.
What are the 2 main types of data structures?
There are two fundamental kinds of data structures: array of contiguous memory locations and linked structures.
Where can arrays be used in real life?
An array is an indexed sequence of elements, all the same type….Real-life examples of arrays include the following:
- post office boxes;
- book pages;
- egg cartons;
- chess/checkerboards.
What are the goals of data structure?
Question: What are the goals of data structure? Answer: 1) Focus on tradeoffs, and reinforce the concept that there are costs and benefits associated with every data structure or algorithm. This is done by describing, for each data structure, the amount of space and time required for typical operations.
What is the structure of data type?
A structured data type is a compound data type which falls under user-defined category and used for grouping simple data types or other compound data types. This contains a sequence of member variable names along with their type/attributes and they are enclosed within curl brackets.
What is the difference between Array and stack?
A stack is a linear data structure in which elements can be inserted and deleted only from one side of the list, called the top….Difference between Stack and Array Data Structures:
| Stacks | Array |
|---|---|
| Stack can contain elements of different data type. | Array contains elements of same data type. |
What is a linked list in programming?
In computer science, a linked list is a linear collection of data elements whose order is not given by their physical placement in memory. Instead, each element points to the next. It is a data structure consisting of a collection of nodes which together represent a sequence.
Why do we need linked lists?
Linked lists are linear data structures that hold data in individual objects called nodes. Linked lists are often used because of their efficient insertion and deletion. They can be used to implement stacks, queues, and other abstract data types.
How linked list is created?
A linked list is formed when many such nodes are linked together to form a chain. Each node points to the next node present in the order. The first node is always used as a reference to traverse the list and is called HEAD. The last node points to NULL.
Where do we use linked list?
Applications of linked list in computer science –
- Implementation of stacks and queues.
- Implementation of graphs : Adjacency list representation of graphs is most popular which is uses linked list to store adjacent vertices.
- Dynamic memory allocation : We use linked list of free blocks.
- Maintaining directory of names.
Which is faster array or linked list?
Memory allocation: For arrays at compile time and at runtime for linked lists. As a result, some operations (such as modifying a certain element) are faster in arrays, while some other (such as inserting/deleting an element in the data) are faster in linked lists.
What type of linked list is best answer?
Discussion Forum
| Que. | What kind of linked list is best to answer question like “What is the item at position n?” |
|---|---|
| b. | Doubly linked list |
| c. | Circular linked list |
| d. | Array implementation of linked list |
| Answer:Array implementation of linked list |
What are the pros and cons of arrays and linked list?
Arrays allow random access and require less memory per element (do not need space for pointers) while lacking efficiency for insertion/deletion operations and memory allocation. On the contrary, linked lists are dynamic and have faster insertion/deletion time complexities.
Why insertion is faster in linked list?
Conclusion: LinkedList element deletion is faster compared to ArrayList. Reason: LinkedList’s each element maintains two pointers (addresses) which points to the both neighbor elements in the list. 3) Inserts Performance: LinkedList add method gives O(1) performance while ArrayList gives O(n) in worst case.
Why are linked lists better than arrays?
Insertion in Array and Linked List. However, unlike arrays which allow random access to the elements contained within them, a link list only allows sequential access to its elements. Arrays, on the other hand, are better suited to small lists, where the maximum number of items that could be on the list is known.
What are disadvantages of a linked list?
More memory is required to store elements in linked list as compared to array. Because in linked list each node contains a pointer and it requires extra memory for itself. Elements or nodes traversal is difficult in linked list.
How big can a linked list get?
A LinkedList doesn’t use an array as the underlying storage, so that doesn’t limit the size. It uses a classical doubly linked list structure with no inherent limit, so its size is only bounded by the available memory. Note that a LinkedList will report the size wrongly if it is bigger than Integer.
What is the difference between array and linked list?
An array is a collection of elements of a similar data type. A linked list is a collection of objects known as a node where node consists of two parts, i.e., data and address. Array elements store in a contiguous memory location. Linked list elements can be stored anywhere in the memory or randomly stored.
What are the advantages and disadvantages of single linked list?
Advantage and Disadvantage of singly Linked list and Doubly Linked list
- Insertions and Deletions can be done easily.
- It does not need movement of elements for insertion and deletion.
- It space is not wasted as we can get space according to our requirements.
- Its size is not fixed.
