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 order traversal of binary search tree will produce −
Answer : C
Explanation
Binary search tree yields a sorted list when traversed in-order.
Q 2 - What data structure is used for breadth first traversal of a graph?
Answer : A
Explanation
Queue is used for breadth first traversal whereas stack is used for depth first traversal.
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 - 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 - An algorithm is
A - a piece of code to be executed.
B - a loosely written code to make final code.
Answer : C
Explanation
An algorithm is a step by step procedure to solve a computer problem.
Q 6 - How many swaps are required to sort the given array using bubble sort - { 2, 5, 1, 3, 4}
Answer : A
Explanation
There will be 3 swaps in first iteration and 1 swap in second iteration.
Q 7 - A queue data-structure can be used for −
Answer : C
Explanation
Queues can be used for limited resource allocation. For other operations, stacks are used.
Q 8 - Recursion uses more memory space than iteration because
A - it uses stack instead of queue.
Answer : B
Explanation
Recursion uses stack but the main reason is, every recursive call needs to be stored separately in the memory.
Q 9 - If we choose Prim's Algorithm for uniquely weighted spanning tree instead of Kruskal's Algorithm, then
A - we'll get a different spanning tree.
B - we'll get the same spanning tree.
Answer : B
Explanation
Regardless of which algorithm is used, in a graph with unique weight, resulting spanning tree will be same.
Q 10 - The worst case complexity of binary search matches with −
Answer : B
Explanation
In the worst case a binary search needs to access all elements of the target list, same as linear search.
