How to iterate over map keys and values in Rust

Answer 1

use std::collections::HashMap;

fn main() {
    let mut map = HashMap::new();
    
    map.insert("Rust", 1);
    map.insert("Python", 2);
    map.insert("C", 3);

    // Iterate over keys and values
    for (key, value) in &map {
        println!("Key: {} Value: {}", key, value);
    }
}



/*
