avlsort

Rust implementation of AVL tree.

This tree holds the rank and the number of duplicates of the elements, and returns them when a new element is added.

Usage

examples/avl.rs

use avlsort::tree::*;

fn main() {
    let v = vec![1, 8, 7, 3, 5, 6, 2, 9, 4, 0, 4, 9];
    let mut g = AvlTree::new();
    println!("=== Push values in v. ===");
    for &i in v.iter() {
        let (rank, dup) = g.push(i);
        println!("value={}| rank={}, dup={}", i, rank, dup);
    }
    println!("Elements in the tree = {}", g.len());
    println!("");

    println!("Height of the tree = {}", g.height());
    println!("How many 4?: {}", g.count(4));
    println!("remove 4: {:?}", g.remove(4));
    println!("4 is in?: {}", g.isin(4));
    println!("remove 4: {:?}", g.remove(4));
    println!("4 is in?: {}", g.isin(4));
    println!("");

    println!("Max value = {}", g.max().unwrap());
    let (value, dup) = g.pop_max_all().unwrap();
    println!("Pop all the max value: value={}, dup={}", value, dup);
    println!("");

    println!("=== Show elements in ascending order. ===");
    loop {
        match g.pop_min() {
            Some(value) => println!("Min value = {}", value),
            None => break,
        }
    }
}
