Questions and Answers

What is a common misconception about bubble sort algorithm?

  • Not suitable for homogeneous data elements in arrays
  • Has a time complexity of O(n log n)
  • Ideal for large number of n (correct)
  • Guaranteed to sort the given array in O(1) time

    • In the context of time complexity in algorithms, what is a common misconception about O(n^3)?

  • It is an efficient time complexity for most algorithms
  • Often confused with O(n log n)
  • Represented by Algorithm Algo1 in the pseudocode examples
  • Typically used for linear search algorithms (correct)

    • Which of the following is an attribute of binary tree data structure?

  • Requires elements to be in a specific order at all times
  • Every node can have only one child (correct)
  • No specific order maintained among elements
  • Has a time complexity of O(log n)
