Techincal Interview Questions - DATA STRUCTURE
DATA STRUCTURE QUESTIONS
- · What is a data structure?
- · What does abstract data type means?
- · Evaluate the following prefix expression " ++ 26 + - 1324" (Similar types can be asked)
- · Convert the following infix expression to post fix notation ((a+2)*(b+4)) -1 (Similar types can be asked)
- · How is it possible to insert different type of elements in stack?
- · Stack can be described as a pointer. Explain.
- · Write a Binary Search program
- · Write programs for Bubble Sort, Quick sort
- · Explain about the types of linked lists
- · How would you sort a linked list?
- · Write the programs for Linked List (Insertion and Deletion) operations
- · What data structure would you mostly likely see in a non recursive implementation of a recursive algorithm?
- · What do you mean by Base case, Recursive case, Binding Time, Run-Time Stack and Tail Recursion?
- · Explain quick sort and merge sort algorithms and derive the time-constraint relation for these.
- · Explain binary searching, Fibinocci search.
- · What is the maximum total number of nodes in a tree that has N levels? Note that the root is level (zero)
- · How many different binary trees and binary search trees can be made from three nodes that contain the key values 1, 2 & 3?
- · A list is ordered from smaller to largest when a sort is called. Which sort would take the longest time to execute?
- · A list is ordered from smaller to largest when a sort is called. Which sort would take the shortest time to execute?
- · When will you sort an array of pointers to list elements, rather than sorting the elements themselves?
- · The element being searched for is not found in an array of 100 elements. What is the average number of comparisons needed in a sequential search to determine that the element is not there, if the elements are completely unordered?
- · What is the average number of comparisons needed in a sequential search to determine the position of an element in an array of 100 elements, if the elements are ordered from largest to smallest?
- · Which sort show the best average behavior?
- · What is the average number of comparisons in a sequential search?
- · Which data structure is needed to convert infix notations to post fix notations?
- · What do you mean by: : Syntax Error , , Logical Error, Runtime Error
- · How can you correct these errors?
- · In which data structure, elements can be added or removed at either end, but not in the middle?
- · How will inorder, preorder and postorder traversals print the elements of a tree?
- · Parenthesis are never needed in prefix or postfix expressions. Why?
- · Which one is faster? A binary search of an ordered set of elements in an array or a sequential search of the elements.

born_star16Yes, if someone has answers to these questions then please share.
*This is very nice "Frooty" -
TheVThank you frooty ,.... Please any one give us the Interview Questions of JAVA, C and DBMS
