Here you can find 1000’s of data structure MCQ questions and interview questions. It includes the objective types of questions on fundamentals of data structure, stack and queue, tree and graph, list and linked list, and searching, merging, and sorting methods in data structure....
Stack,Hashtable,Array. But looking at the larger scope and usage, Java 1.2 came up with Collections Framework that group all the collections interfaces, implementations and algorithms. Java Collections have come through a long way with usage of Generics and Concurrent...
We will use a stack data structure, to keep track of asteroids that haven’t yet collided and in the end, we will just return the stack representing the final state of the asteroids left or the asteroids that did not get destroyed after all the collisions. Iterate Through Each Asteroid: ...
what is stack & queue? Macros are preprocessor directives that are defined using #define directive. Macros consist of two parts Macro_Name, & Macro_Substitution_Text. Before the source code gets complied, the preprocessor will check for the presence of macros. & wherever it found that macro si...
Collections are used in every programming language and initial java release contained few classes for collections: Vector, Stack, Hashtable, Array. But looking at the larger scope and usage, Java 1.2 came up with Collections Framework that group all the collections interfaces, implementations and alg...
In Java, when an object is no longer used or referenced, garbage collection is called and the object is destroyed automatically. 6) What's the difference between Stack and Queue? The difference between a stack and a queue is that stack is based on the Last in First out (LIFO) principle...
How would you implement a queue from a stack? Write a funtion that finds repeating characters in a string. Write a routine to reverse a series of numbers without using an array. Give me an algorithm for telling me the number I didn't give you in a given range of numbers. (Numbers are...
19. Describe the difference between a stack and a queue. A stack and a queue are both fundamental data structures used in computer programming, but they differ in their principles of data organization and access. A stack follows the Last-In-First-Out (LIFO) principle, meaning that the last...
Awake–>OnEnable->Start.OnEnablecan occur repeatedly in the same cycle! 5. Question: What is the difference between stack and queue? Answer Stacks and queuesare both data structures that organise and manage collections of elements, but they differ in how elements are added and removed. ...
