Counting Sort Algorithm

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

For Counting Sort Algorithm, time vs memory is in play. Don’t blame it until you have traced names A→Z.

Skip Counting Sort Algorithm and unstable sort when equal keys matter shows up in the roll list.

Vikram ships Counting Sort Algorithm in the roll list. That is the use case worth saying.

Counting Sort Algorithm trap — unstable sort when equal keys matter. Vikram loses marks for that every viva.

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

Close Counting Sort Algorithm with: “If I skip it, names A→Z goes wrong like this: unstable sort when equal keys matter.”

Exam tip

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

Example

# Counting Sort Algorithm
data = [4, 1, 3]
print("start", data)
if data[0] > data[1]:
    data[0], data[1] = data[1], data[0]
print("after one step", data)

Counting Sort Algorithm: dry-run [4, 1, 3]. Say the list after one step.

Short notes

DefCounting Sort Algorithm — Vikram uses it for names A→Z in the roll list.
RuleCounting Sort Algorithm → n log n vs n².
RememberCounting Sort Algorithm + time vs memory (the roll list).
UseCounting Sort Algorithm in the roll list (names A→Z).
TrapCounting Sort Algorithm — unstable sort when equal keys matter.
ExCounting Sort Algorithm → names A→Z.
