Data Structure and Algorithm Quiz

What is the difference between an array and a linked list?

• Color and size

• Input and output

• Speed and efficiency

• Memory allocation and structure

Explain the working of the bubble sort algorithm with an example.

• Bubble sort works by comparing adjacent elements and swapping them if they are in the wrong order.

• Bubble sort works by comparing every element with the first element and swapping them if they are in the wrong order.

• Bubble sort works by sorting the elements in descending order.

• Bubble sort works by comparing elements at random and swapping them if they are in the wrong order.

What is the time complexity of binary search?

• O(n)

• O(1)

• O(n^2)

• O(log n)

How does a stack differ from a queue?

• A stack and a queue are the same and can be used interchangeably.

• A stack follows the First In First Out (FIFO) principle, while a queue follows the Last In First Out (LIFO) principle.

• A stack can only store integers, while a queue can only store strings.

• A stack follows the Last In First Out (LIFO) principle, while a queue follows the First In First Out (FIFO) principle.

Explain the concept of memoization in dynamic programming.

• Memoization is a technique used to slow down the function calls.

• Memoization is a technique used to delete the results of function calls.

• Memoization is a technique used to only store the results of function calls for the first time they occur.

• Memoization is a technique used to store the results of expensive function calls and reuse them when the same inputs occur again.

What is the time complexity of the quicksort algorithm?

• O(1)

• O(n log n)

• O(n^2)

• O(n!)

Compare the performance of a stack implemented using an array versus a linked list.

• The performance of a stack using an array is always better than a linked list.

• It depends on the specific operations and requirements of the application.

• The performance of a stack using a linked list is always better than an array.

• The performance of a stack using an array and a linked list is the same.

What is the significance of dynamic programming in solving optimization problems?

• It only works for simple problems

• It makes problems more complex and time-consuming

• It breaks down complex problems into simpler subproblems, reducing time complexity and improving efficiency.

• It has no impact on time complexity or efficiency

Discuss the applications of breadth-first search algorithm.

• Option B

• Option A

• Option D

• Option C

How does a priority queue differ from a regular queue?

• Elements are removed based on their size.

• Elements are removed randomly.

• Elements are removed based on their insertion order.

• Elements are removed based on their priority.
