Data Structures and Algorithms Questions

Multiple choice

Merge sort's average case space complexity is

  1. 0

  2. O(n)

  3. O(logn)

  4. None of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Merge sort is a divide and conquer algorithm that requires auxiliary space proportional to the number of elements being sorted, resulting in O(n) space complexity.

Multiple choice

Quick sort's average case space complexity is

  1. 0

  2. O(n)

  3. O(logn)

  4. None of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Quick sort requires stack space for recursive function calls. On average, the recursion tree depth is logarithmic, leading to an average case space complexity of O(logn).

Multiple choice

For which product you might create a schema?

  1. E-mail message

  2. Database

  3. Greeting card

  4. Save game file
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In the context of databases, a schema is the structural definition that outlines how data is organized and the relationships between tables.

Multiple choice

Linked list is a ............

  1. Linear Data Structure

  2. Non-Linear Data Structure

  3. Both of these

  4. None of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

 According to the way, linked list is accessed, it is linear data structure and according to storage, linked list is a non-linear data structure. Hence this is the answer.
