Expand description

CartesianTree

inorder が元配列の順になる(二分木としての中順走査が 0..n-1)

build_max は max-heap(親の値 (\ge) 子の値). build_min は min-heap(親の値 (\le) 子の値).

Implementations§

Source§

impl<T: Ord> CartesianTree<T>

Source

pub fn build_by<F>(arr: &[T], should_pop: F) -> Self
where F: FnMut(&T, &T) -> bool,

共通実装.

should_pop(top, cur) が true の間,スタックを pop する.

Source

pub fn build_max(arr: &[T]) -> Self

max-heap の Cartesian Tree を構築する(同値は右側優先).

すなわち,区間の最大値(同値なら最右)を根にして再帰分割した木になる.

Source

pub fn build_min(arr: &[T]) -> Self

min-heap の Cartesian Tree を構築する(同値は右側優先).

すなわち,区間の最小値(同値なら最右)を根にして再帰分割した木になる.
