find the median of all values in a map in rust

To find the median of all the values in a map in Rust, we can follow these steps:

1. Get all the values from the map using the values() method.
2. Convert the values iterator into a vector using the collect() method.
3. Sort the vector using the sort() method from the standard library.
4. Compute the median of the sorted vector using the median() method from the statistics crate.

Here is the Rust code that demonstrates these steps:

main.rs
use std::collections::HashMap;
use statistics::median;

fn main() {
    let mut map = HashMap::new();
    map.insert("a", 1);
    map.insert("b", 2);
    map.insert("c", 3);

    let values: Vec<_> = map.values().cloned().collect(); // Step 1 and 2
    let median = median(&values); // Step 3 and 4

    println!("Median: {}", median);
}

This code creates a HashMap with some key-value pairs, gets the values iterator using the values() method, converts it into a vector using collect(), sorts the vector using the sort() method (which is called by the median() method from the statistics crate), and computes the median of the sorted vector using the median() method. The output of this program should be:

main.rs
Median: 2
