Ordered statistic tree
WebHere is the updated algorithm, which maintains the size information: Insert (Tree, x) If Tree is empty, set Tree to be x and size (Tree)=1, and return. Increase size (Tree) by 1. Let r be the root of Tree, and Left, Right its children. If x < r then call Insert (Left, x ), otherwise call Insert (Right, x ). This is the basic idea. WebAdds order statistics to each node and the tree itself: report a value position in sorted list. report the count of values above and below a certain value. report percentile, median, rank, etc. find the value with a given percentile rank.
