Questions & Step-by-Step Solutions

What is the primary disadvantage of using Quick Sort?
  • Step 1: Understand what sorting algorithms are. They are methods used to arrange data in a specific order.
  • Step 2: Learn about Quick Sort. It is a popular sorting algorithm that works by dividing the data into smaller parts.
  • Step 3: Know what 'stable' means in sorting. A stable sorting algorithm keeps equal elements in the same order they appeared in the original list.
  • Step 4: Identify the primary disadvantage of Quick Sort. It does not guarantee that equal elements will stay in the same order after sorting.
  • Step 5: Conclude that the primary disadvantage of Quick Sort is that it is not a stable sorting algorithm.
