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 - Which of the following asymptotic notation is the worst among all?
Answer : B
Explanation
Ο(n+9378) is n dependent
Ο(n3) is cubic
nΟ(1) is polynomial
2Ο(n) is exponential
Q 4 - Which of the following algorithm is not stable?
Answer : B
Explanation
Among the given, only quick sort is not stable that is it may re-arrange the already sorted items.
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 - In context with time-complexity, find the odd out −
A - Deletion from Linked List.
Answer : D
Explanation
Binary heap heapify operation has time-complexity of Ο(n), while other operations have time-complexity of Ο(1) only.
Q 7 - Which of the following uses memoization?
B - Divide and conquer approach
Answer : C
Explanation
Remembering the results of previously calculated solutions is called memoization.
Q 8 - Program with highest run-time complexity is
Answer : A
Explanation
Tower of hanoi has the highest run time complexity
Q 9 - Access time of a binary search tree may go worse in terms of time complexity upto
Answer : C
Explanation
At maximum, BST may need to search all n values in the tree in order to access an element, hence, Ο(n).
Q 10 - Apriori analysis of an algorithm assumes that −
A - the algorithm has been tested before in real environment.
B - all other factors like CPU speed are constant and have no effect on implementation.
Answer : B
Explanation
Efficiency of algorithm is measured by assuming that all other factors e.g. processor speed, are constant and have no effect on implementation.
