As per my experience good interviewers hardly plan to ask any particular question during your interview, normally questions start with some basic concept of the subject and later they continue based on further discussion and what you answer:  \nWhat is data-structure?  \nData structure is a way of defining , storing & retriving of data in a structural & systemetic way. A data structure may contain different type of data items.  \nWhat are various data-structures available?  \nData structure availability may vary by programming languages. Commonly available data structures are list, arrays, stack, queues, graph , tree etc .  \nWhat is algorithm?  \nAlgorithm is a step by step procedure , which defines a set of instructions to be executed in certain order to get the desired output.  \nWhy we need to do algorithm analysis?  \nA problem can be solved in more than one ways. So , many solution algorithms can be derived fora given problem . We analyze available algorithms to find and implement the best suitable algorithm .  \nWhat are the criteria of algorithm analysis?  \nAn algorithm are generally analyzed on two factors − time and space . That is, how much execution time and how much extra space required by the algorithm .  \nWhat is asymptotic analysis of an algorithm?  \nAsymptotic analysis of an algorithm , refers to defining the mathematical boundation/framing of its run-time performance . Using asymptotic analysis, we can very well conclude the best case , average case and worst case scenario of an algorithm .  \nWhat are asymptotic notations?  \nAsymptotic analysis can provide three levels of mathematical binding of execution time of an algorithm −  \n Best case is represented by Οn notation.  \n Worst case is represented by Ωn notation.  \n Average case is represented by Θn notation.  \nWhat is linear data strucutre?  \nA linear data-strucutre has sequentially arranged data items. The next time can be located in the next memory address. It is stored and accessed in a sequential manner . Array and list are example of linear data structure .  \nWhat are common operations that can be performed on a data-structure?  \nThe following operations are commonly performed on any data-structure −  \n Insertion − adding a data item  \nDeletion − removing a data item  \n Traversal − accessing and/or printing all data items  \n Searching − finding a particular data item  \n Sorting − arranging data items in a pre-defined sequence Briefly explain the approaches to develop algorithms.  \nThere are three commonly used approaches to develop algorithms −  \n Greedy Approach − finding solution by choosing next best option  \n Divide and Conquer − diving the problem to a minimum possible sub-problem and solving them independently  \n Dynamic Programming − diving the problem to a minimum possible sub-problem and solving them combinedly  \nGive some examples greedy algorithms.  \nThe below given problems find their solution using greedy algorithm approach −  \n Travelling Salesman Problem  \n Prim 's Minimal Spanning Tree Algorithm  \n Kruskal 's Minimal Spanning Tree Algorithm  \n Dijkstra 's Minimal Spanning Tree Algorithm  \n Graph-Map Coloring  \n Graph-Vertex Cover  \n Knapsack Problem  \n Job Scheduling Problem  \nWhat are some examples of divide and conquer algorithms?  \nThe below given problems find their solution using divide and conquer algorithm approach −  \n Merge Sort  \n Quick Sort  \n Binary Search  \n Strassen 's Matrix Multiplication  \n Clos","cbCaisrwGhdDPdvB","https://ap.wps.com/l/cbCaisrwGhdDPdvB","pdf",68933,"English","# Interview Question Foundations\n## Data structures basics\n## Algorithms and algorithm analysis\n## Asymptotic analysis and notations\n## Linear data structures and common operations\n# Algorithm Approaches and Examples\n## Greedy algorithms\n## Divide and Conquer algorithms\n## Dynamic Programming algorithms\n## Additional DSA concepts (linked list, stack, queue)","[{\"question\":\"What is a data structure and what purpose does it serve?\",\"answer\":\"A data structure defines how data is structured, stored, and retrieved in a systematic way.
