Questions & Step-by-Step Solutions

Which of the following is true about Quick Sort?
  • Step 1: Understand what Quick Sort is. It is a sorting algorithm that organizes data in a specific order, usually from smallest to largest.
  • Step 2: Learn that Quick Sort works by selecting a 'pivot' element from the array and partitioning the other elements into two groups: those less than the pivot and those greater than the pivot.
  • Step 3: Know that Quick Sort can be implemented using recursion, which means it calls itself to sort the smaller groups of data.
  • Step 4: Recognize that Quick Sort is not a stable sorting algorithm. This means that it does not necessarily preserve the original order of equal elements.
