Binary indexed tree range update
WebJan 10, 2015 · The first is a simple range update/point query tree. When you update A to B with V, in practice you add V to position A, so any prefix query X>=A is affected by it. Then you remove V from B+1, so any query X >= B+1 doesn't see the V added to A. No surprises here. Prefix query to the range update/point tree WebFeb 26, 2024 · Range Update and Range Query; 1.
