Difference between merge sort and quick sort

Difference between merge sort and quick sort is a DSA idea you prove with names A→Z, not with a slogan.

Difference between merge sort and quick sort on the board: n log n vs n². Then say what names A→Z looks like after.

Without Difference between merge sort and quick sort, the roll list gets messy and names A→Z is hard to trust.

Difference between merge sort and quick sort shows up in the roll list. Name names A→Z, not “a real-world scenario”.

Difference between merge sort and quick sort miss: unstable sort when equal keys matter. Fix it before you talk about advanced DSA.

One breath for Difference between merge sort and quick sort, then names A→Z, then unstable sort when equal keys matter. Sit down.

Exam tip

Board: names A→Z. Dry-run Difference between merge sort and quick sort. Name the trap: unstable sort when equal keys matter.

Example

def quick_sort(arr):
    if len(arr) <= 1:
        return arr
    pivot = arr[len(arr) // 2]
    left = [x for x in arr if x < pivot]
    mid = [x for x in arr if x == pivot]
    right = [x for x in arr if x > pivot]
    return quick_sort(left) + mid + quick_sort(right)

print(quick_sort([5, 1, 4, 2, 3]))

Difference between merge sort and quick sort — quick sort partitions around a pivot, then sorts both sides.
