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 - In a min-heap:
A - parent nodes have values greater than or equal to their childs
B - parent nodes have values less than or equal to their childs
Answer : A
Explanation
In a min heap, parents always have lesser or equal values than that of their childs.
Q 2 - What data structure can be used to check if a syntax has balanced paranthesis ?
Answer : D
Explanation
Stack uses LIFO method which is good for checking matching paranthesis.
Q 3 - Minimum number of moves required to solve a Tower of Hanoi puzzle is
Answer : C
Explanation
Minimum number of moves required to solve a Tower of Hanoi puzzle is 2n - 1. Where n is the number of disks. If the number of disks is 3, then minimum number of moves required are 23 - 1 = 7
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 - Which of the following has search effeciency of Ο(1) −
Answer : C
Explanation
A simple hash table has the Ω(1) efficiency.
Q 6 - Which of the below given sorting techniques has highest best-case runtime complexity −
Answer : B
Explanation
Selection sort best case time complexity is Ο(n2)
Q 7 - Which of the following is not possible with an array in C programming langauge −
Answer : C
Explanation
Array in C are static and cannot be shrinked or expanded in run-time.
Q 8 - In a min heap
A - minimum values are stored.
B - child nodes have less value than parent nodes.
Answer : C
Explanation
In a min heap, parent nodes store lesser values than child nodes. The minimum value of the entire heap is stored at root.
Answer : A
Explanation
Shell sort uses insertion sort when interval value is 1.
Q 10 - If the data collection is in sorted form and equally distributed then the run time complexity of interpolation search is −
Answer : D
Explanation
Runtime complexity of interpolation search algorithm is Ο(log (log n)) as compared to Ο(log n) of BST in favourable situations.
