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 - What is the worst case run-time complexity of binary search algorithm?
Answer : D
Explanation
In the worst case, binary search will be left or right intended, making it compare all the n values.
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 - Find the odd out
A - Prim's Minimal Spanning Tree Algorithm
B - Kruskal's Minimal Spanning Tree Algorithm
Answer : C
Explanation
Floyd-Warshall's All pair shortest path Algorithm uses dynamic programming approach. All other mentioned algorithms use greedy programming approach
Answer : C
Explanation
Every connected graph at least has one spanning tree.
Q 5 - Which of the below given series is Non-Increasing Order −
Answer : C
Explanation
A sequence of values is said to be in non-increasing order, if the successive element is less than or equal to its previous element in the sequence.
Q 6 - Match the following −
| (1) Bubble Sort | (A) Ο(n) |
| (2) Shell Sort | (B) Ο(n2) |
| (3) Selection Sort | (C) Ο(n log n) |
Answer : B
Explanation
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 - A pivot element to partition unsorted list is used in
Answer : B
Explanation
The quick sort partitions an array using pivot element and then calls itself recursively twice to sort the resulting two subarray.
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.
