Data Structures Algorithms Online Quiz
Following quiz provides Multiple Choice Questions (MCQs) related to Data Structures Algorithms. You will have to read all the given answers and click over the correct answer. If you are not sure about the answer then you can check the answer using Show Answer button. You can use Next Quiz button to check new set of questions in the quiz.
Q 1 - A procedure that calls itself is called
Answer : C
Explanation
In recursion, a procedure calls itself, either directly or by calling a procedure which in turn calls it.
Answer : B
Explanation
In queue, data item inserted first, will be available first and data item inserted last will be available in the last. FIFO stands for First In First Out and is a correct answer.
Q 3 - Travelling salesman problem is an example of
Answer : B
Explanation
Travelling salesman is an example of greedy algorithm. Greedy algorithms tries to find localized optimum solution which may eventually land in globally optimized solutions.
Q 4 - What could be the worst case height of an AVL tree?
Answer : C
Explanation
Worst case height of an AVL tree is 1.44 log n
Q 5 - After each iteration in bubble sort
A - at least one element is at its sorted position.
Answer : A
Explanation
In one iteration of Bubble sort, the maximum of the set in hand is moved at the end of the unsorted list. Hence one less comparison.
Q 6 - What will be the running-time of Dijkstra's single source shortest path algorithm, if the graph G(V,E) is stored in form of adjacency list and binary heap is used −
Answer : C
Explanation
The runing time will be Ο(|E|+|V| log |V|) when we use adjacency list and binary heap.
Q 7 - Index of arrays in C programming langauge starts from
Answer : A
Explanation
Arrays, in C, starts from 0 which is mapped to its base address.
Q 8 - Program with highest run-time complexity is
Answer : A
Explanation
Tower of hanoi has the highest run time complexity
Q 9 - The following sorting algorithms maintain two sub-lists, one sorted and one to be sorted −
Answer : D
Explanation
Both selection sort and insertion sort maintains two sublists and then checks unsorted list for next sorted element.
Q 10 - Aposterior analysis are more accurate than apriori analysis because −
A - it contains the real data.
B - it assumes all other factors to be dynamic.
Answer : B
Explanation
In this analysis, actual statistics like running time and space required, are collected.
