What is data structure in MCQS?

What is data structure in MCQS?

Data Structure is a way used in programming that can store and organise data efficiently when required. The efficient processing can be space, time, or both. It can be based on other factors as a priority needed for some specific problem.

Which of the following is a type of data structure Mcq?

Linear Data Structures: Arrays. Non-Linear Data Structures: LinkedList, Trees, etc.

What is abstract data type in data structure Mcq?

1. Abstract Data Types. The section contains multiple choice questions and answers on arrays, stacks, queues, single linked lists, doubly and circular linked lists, stacks using arrays and linked lists, queues using arrays, stacks and linked lists, priority queues and double ended queues.

Which data structure is used by map Mcq?

The map data type is referred to as an associative array because, like an array, it is a collection of values rather than a single value, as an Int or a String is. Furthermore, each distinct key is associated with a value, resulting in an associative array.

What is an algorithm Mcq?

Answer: a. Explanation: An algorithm is a stepwise solution to the problem. 2. An algorithm in which we divide the problem into subproblem and then we combine the subsolutions to form solution to the original problem is known as _________ a) Brute Force.

Is the type of queue?

There are four different types of queues: Simple Queue. Circular Queue. Priority Queue.

Which is an abstract data type?

In computer science, an abstract data type (ADT) is a mathematical model for data types. An abstract data type is defined by its behavior (semantics) from the point of view of a user, of the data, specifically in terms of possible values, possible operations on data of this type, and the behavior of these operations.

Why stack is called ADT?

stack and queue are referred as abstract datatype because in stack there are, mainly two operations push and pop and in queue there are insertion and deletion. Which are when operated on any set of data then it is free from that which type of data that must be contained by the set.

Is array an abstract data type?

The array is a basic abstract data type that holds an ordered collection of items accessible by an integer index.

Is hash table a data structure?

In computing, a hash table, also known as hash map, is a data structure that implements an associative array or dictionary. It is an abstract data type that maps keys to values.

What is the use of a hash function?

Hash functions are used for data integrity and often in combination with digital signatures. With a good hash function, even a 1-bit change in a message will produce a different hash (on average, half of the bits change). With digital signatures, a message is hashed and then the hash itself is signed.

What is the return type open () method?

What is the return type open() method? Explanation: open() method returns a bool value indicating whether the file is opened or some error has occurred. 10.

What is FIFO algorithm Mcq?

Solution(By Examveda Team)

The first-in, first-out (FIFO) page replacement algorithm is a low-overhead algorithm that requires little bookkeeping on the part of the operating system. In simple words, on a page fault, the frame that has been in memory the longest is replaced.

What is stack in C?

A stack is a linear data structure, collection of items of the same type. Stack follows the Last In First Out (LIFO) fashion wherein the last element entered is the first one to be popped out. In stacks, the insertion and deletion of elements happen only at one endpoint of it.

What are the types of stack?

Types of Stack. There are two types of stacks they are register stack and the memory stack.

What primitive data types?

Primitive data types – includes byte , short , int , long , float , double , boolean and char. Non-primitive data types – such as String , Arrays and Classes (you will learn more about these in a later chapter)

Is stack LIFO or FIFO?

The primary difference between Stack and Queue Data Structures is that Stack follows LIFO while Queue follows FIFO data structure type. LIFO refers to Last In First Out. It means that when we put data in a Stack, it processes the last entry first.

What is a heap tree?

In computer science, a heap is a specialized tree-based data structure which is essentially an almost complete tree that satisfies the heap property: in a max heap, for any given node C, if P is a parent node of C, then the key (the value) of P is greater than or equal to the key of C.

Is ArrayList an ADT?

As ArrayList is itself one of those concrete implementations that uses Java generics to define the data type it operates on, it is itself an abstract data structure, but in a different way from interfaces or abstract classes. The abstract data structure is, in this sense, an ill-defined term.

Is array a data structure?

What Are Arrays in Data Structures? An array is a linear data structure that collects elements of the same data type and stores them in contiguous and adjacent memory locations.

Which algorithm is used for hash password?

Commonly used hashing algorithms include Message Digest (MDx) algorithms, such as MD5, and Secure Hash Algorithms (SHA), such as SHA-1 and the SHA-2 family that includes the widely used SHA-256 algorithm.

How many types of hashing are there?

Types of Hashing
There are many different types of hash algorithms such as RipeMD, Tiger, xxhash and more, but the most common type of hashing used for file integrity checks are MD5, SHA-2 and CRC32. MD5 – An MD5 hash function encodes a string of information and encodes it into a 128-bit fingerprint.

Can main () function be made private?

Yes, we can declare the main method as private in Java. It compiles successfully without any errors but at the runtime, it says that the main method is not public.

What is this operator called?

Logical (or Relational) Operators:

What is full form FIFO?

FIFO = First In First Out
FIFO means that products stored first are to be retrieved first.
