Disadvantage: There is no guarantee of finding an unoccupied cell once the table is nearly half full.

A collection of non-empty disjoint sets S=S1,S2,â€¦.,Sk i.e;each Si is a non-empty set that has no element in common with any other Sj. In mathematical notation this is: Siâˆ©Sj=Ð¤. Each set is identified by a unique element called its representative.

An undirected graph is connected, if there is a path from every vertex to every other vertex. A directed graph with this property is called strongly connected.

When a directed graph is not strongly connected but the underlying graph is connected, then the graph is said to be weakly connected.

Actually macro and function are used for different purposes. A macro replaces its expression code physically in the code at the time of preprocessing. But in case of function the control goes to the function while executing the code. So when the code is small then it is better to use macro. But when code is large then function should be used.

The isEmpty() member method is called within the dequeue process to determine if there is an item in the queue to be removed i.e. isEmpty() is called to decide whether the queue has at least one element. This method is called by the dequeue() method before returning the front element.

No! Minimal spanning tree assures that the total weight of the tree is kept at its minimum. But it doesnâ€™t mean that the distance between any two nodes involved in the minimal-spanning tree is minimum.

In general: There are 2n-1 nodes in a full binary tree. By the method of elimination:

Full binary trees contain odd number of nodes. So there cannot be full binary trees with 8 or 14 nodes, so rejected. With 13 nodes you can form a complete binary tree but not a full binary tree. So the correct answer is 15.

1. Serving requests on a single shared resource, like CPU task scheduling, printer, etc.

2. Handling interruptions in real-time systems.

3. Buffers in apps like CD player and MP3 media players

4. In maintaining a playlist in media players, like adding or removing songs.

It depends on where you plan to use Linked lists. You can consider a linked list for both non-linear and linear data structures. When used for data storage, it is regarded as a non-linear data structure. When used for access strategies, it is considered a linear data structure.

A linked list is a series of data structures connected via links. In simple words, it's a sequence of links that contain items. After the array, the linked list is the second most used data structure. The essential terms to understand the linked list are:

Link - In a linked list, each link stores data called an element.

Next - In a linked list, each link is connected to the following link called next.

LinkedList - It contains the connection link to the first link called first.

Basic operations supported by a linked list:

Insertion - Inserts an element at the list beginning.

Deletion - Deletes an element at the list beginning.

Display - Displays the complete list.

Search - Searches an element using the given key.

Delete - Deletes an element using the given key.

Mainly the following operations are performed on a stack:

1. Push operation: To add an item to the stack. If the stack is complete, then it is in an overflow condition.

2. Pop operation: It is used to remove an item from the stack. If it's an empty stack, then it is in underflow condition.

3. isEmpty operation: If the stack is empty returns true, else false.

4. Peek or Top operation: This returns the top element of the stack.

To implement the LRU cache, you should use two data structures: a hashmap and a doubly linked list.

A hashmap helps with the lookup of cached keys, and a doubly-linked list helps maintain the eviction order.

Using two stacks, you can implement a queue. The purpose is to complete the queue's en queue operation so that the initially entered element always ends up at the top of the stack.

1. First, to enqueue an item into the queue, migrate all the elements from the beginning stack to the second stack, push the item into the stack, and send all elements back to the first stack.

2. To dequeue an item from the queue, return the top item from the first stack.

Yes, you can implement a stack using two queues. Any data structure to act like a stack should have a push() method to add data on top and a pop() method to remove the top data.

The following are the steps that you need to follow to insert the data into the tree:

1. First of all, check whether the data is unique or not ( i.e. check whether the data that you are going to insert doesnâ€™t already exist in the tree).

2. Then check if the tree is empty. If the tree is empty then all you need to do is just insert a new item into the root. If the key is smaller than that of a rootâ€™s key then insert that data into the rootâ€™s left subtree or otherwise, insert the data into the right side of the rootâ€™s subtree.

A spanning tree is a subset of a graph that has all the vertices but with the minimum number of edges necessary.

A queue is a type of linear structure which is used to access components that support the FIFO (First In First Out) method. Dequeue, enqueue, front, and rear are key queue functions. Unlike a stack, the arrays and linked lists are used to enforce a queue.

The element most recently added is removed first in a stack. However, in the event of a queue, the element least recently added is removed first.

Following are the different operation that are generally carried out in Data Structures:

Insertâ€“ Add a new data item in the already existing set of data items.

Deleteâ€“ Remove an existing data item from the given data item set.

Traverseâ€“ Access each piece of data precisely once so that it can be processed.

Searchâ€“ Figure out where the data item resides in the specified data item set.

Sortâ€“ Arrange the data objects in certain order i.e. in ascending or descending order for numerical data and in dictionary order for alphanumeric data.
