Questions & Step-by-Step Solutions
In which scenario is Quick Sort generally faster than Merge Sort?
Step 1: Understand that Quick Sort and Merge Sort are both sorting algorithms used to arrange data in a specific order.
Step 2: Recognize that Quick Sort works by selecting a 'pivot' element and partitioning the array into smaller parts based on that pivot.
Step 3: Note that Merge Sort divides the array into two halves, sorts each half, and then merges them back together.
Step 4: Realize that Quick Sort can be faster than Merge Sort when the array is nearly sorted because it can quickly partition the data with fewer comparisons.
Step 5: Understand that Merge Sort always takes a consistent amount of time to sort, regardless of the initial order of the array, while Quick Sort can take advantage of the existing order.
