Compressed segment trees and merging sets in O(N*logN)

Compressed segment trees and merging sets in O(N*logN) is a DSA topic. In plain words you use it for a short Compressed segment trees and merging sets in ON*logN example in a short dry-run on paper. Don’t start with a slogan — start with that picture.

Smallest example: the smallest Compressed segment trees and merging sets in ON*logN example you can type. Type it, run it, and say what you see. If you can do that from memory, you know Compressed segment trees and merging sets in O(N*logN).

From the example next to this theory — Compressed segment trees and merging sets in O(N*logN): dry-run [4, 1, 3].

Trap: only saying “Compressed segment trees and merging sets in ON*logN” with no example. Fix that before you talk about advanced DSA.

Viva: what is Compressed segment trees and merging sets in O(N*logN)? Then show the smallest Compressed segment trees and merging sets in ON*logN example you can type. Then name the trap.

What is Compressed segment trees and merging sets in O(N*logN)? Show this: the smallest Compressed segment trees and merging sets in ON*logN example you can type. Trap: only saying “Compressed segment trees and merging sets in ON*logN” with no example.

Example

# Compressed segment trees and merging sets in O(N*logN)
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)

Compressed segment trees and merging sets in O(N*logN): dry-run [4, 1, 3]. Say the list after one step.
