Questions and Answers

What is the primary objective of this course?

  • To implement sorting algorithms in Java
  • To differentiate sorting algorithms in Java (correct)
  • To explain the concept of simple sorting
  • To analyze the performance of sorting algorithms

    • Which step is involved in all three sorting algorithms?

  • Dividing the data into two parts
  • Removing the largest item
  • Swapping two items or copying one item (correct)
  • Comparing three items

    • What is the key characteristic of a bubble sort?

  • It involves swapping adjacent elements if they are in the wrong order (correct)
  • It divides the data into smaller chunks for comparison
  • It always requires comparing all items at once
  • It is guaranteed to be faster than other sorting algorithms
