Recursive Bubble Sort

Don’t start Recursive Bubble Sort with jargon. Start with names A→Z. That is the whole point.

Recursive Bubble Sort on the board — n log n vs n². Then say what names A→Z looks like after.

Without Recursive Bubble Sort, the roll list gets messy and names A→Z is hard to trust.

Use Recursive Bubble Sort when names A→Z must stay clear. If a simpler DSA step works, use that instead.

Recursive Bubble Sort trap — unstable sort when equal keys matter. Kabir loses marks for that every viva.

Place Recursive Bubble Sort next to nearby DSA work — n log n vs n² is the link.

One breath for Recursive Bubble Sort, then names A→Z, then unstable sort when equal keys matter. Sit down.

Exam tip

Board: names A→Z. Dry-run Recursive Bubble Sort. Name the trap: unstable sort when equal keys matter.

Example

def bubble_sort(arr):
    a = arr[:]
    n = len(a)
    for i in range(n):
        for j in range(0, n - i - 1):
            if a[j] > a[j + 1]:
                a[j], a[j + 1] = a[j + 1], a[j]
    return a

print(bubble_sort([5, 1, 4, 2]))

Recursive Bubble Sort — bubble sort swaps adjacent out-of-order pairs repeatedly.
