Wiley Mthree Interview Questions for Freshers
This section will discuss the fundamental questions of Wiley Mthree interview questions to establish a solid base.
1. What is array data structure?
Ans: A data structure called an array is used to store data in a form that is both effective and simple to retrieve. It keeps information in succession, just like a list.
Multiple arrays are combined to form an array data structure. The data of each collection is then saved in the sequence in which they were created, and each array is given a unique identification number.
2. What is a queue data structure? What are the applications of the queue?
Ans: A queue is described as a linear data structure with open ends and First In First Out (FIFO) execution of operations. Users can systematically store things in a list using a queue linear data structure. Until the back of the line is full, more things are added; once that happens, the front of the queue is cleared of the items.
The following are a few uses for the queue data structure:
• Graphs with a breadth-first search algorithm
• Operating system: Scheduling of tasks, disk, and CPU planning, etc.
• Call center call management
3. What is an asymptotic analysis of an algorithm?
Ans: The runtime performance of an algorithm is determined by its asymptotic analysis and mathematical bounds.
The best case (Omega Notation), average case (Theta Notation), and worst case (Big Oh Notation, O) performance of an algorithm may all be expressed using asymptotic analysis.
4. What is a priority queue? What are the applications for the priority queue?
Ans: An abstract data type called a Priority Queue is like a queue in that each member has a priority value. The priority of the components in a priority queue determines the order in which they are served. The details are performed in the order they appear in the line if they have the same priority. Here are a few real-time priority queue applications.
• Used in graph algorithms such as Prim's Minimum Spanning Tree and Dijkstra.
• Huffman data compression code.
• To find the Kth Largest/Smallest Element
5. What is binary search tree data structure?
Ans: A binary search tree is a data structure that keeps things in sorted order. Each node in a binary search tree holds a key and a value. The object is accessed using the key, and its presence or absence is determined using the value.
Any value, including an integer, a floating point number, a character string, or even a mix of these, can serve as the key.
Any object, including an integer, a floating point number, a character string, or even a combination of these, may be used as the value.
A node's key is used to access the item stored there when it is added to the tree. A node is eliminated from the tree when its key is used to access the object stored at that node.
6. What are virtual functions?
Ans: When inheritance is employed, virtual functions are called based on the type of the object being pointed at or referenced, not the type of the pointer or reference. In other words, the runtime is when virtual function resolution occurs. A function can be made virtual by using the term virtual.
7. What are VTABLE and VPTR?
Ans: A table of function pointers is called the vtable. It is kept for each class. Vtable is pointed to by vptr. It is kept up for each thing. The compiler inserts extra code twice to utilize and maintain vtable and vptr.
Every constructor contains code. The vptr of the object being formed is set by this code. This code causes vptr to point to the class's vtable.
