Which of the following sorting algorithms is not in-place?

Step 1: Understand what an in-place sorting algorithm is. An in-place sorting algorithm sorts the data without needing extra space for another array.
Step 2: Identify the sorting algorithms being compared. Common sorting algorithms include Merge Sort, Quick Sort, and Bubble Sort.
Step 3: Analyze Merge Sort. Merge Sort divides the array into smaller parts, sorts them, and then merges them back together.
Step 4: Note that during the merging process, Merge Sort requires additional space to hold the merged data.
Step 5: Conclude that because Merge Sort uses extra space for merging, it is not an in-place sorting algorithm.
