When I started learning Rust (2021.11.03), the first thing I encountered was printing a square and a triangle. I was confused at first. Then, when I understood how to write simple algorithms, I decided to write an algorithm for printing a Christmas tree. And in January 2022 I got this:
This is the algorithm
use std::thread; use std::time::Duration; fn main() { tannenbaum(7) } fn tannenbaum(x: i32) { let mut top = 0; let mut i = 1; while top < x/2 { for _empty_space in 0..2 { print!(" ") } top += 1 } if x%2 == 1 { print!(" ") } println!("A"); while i <= x { for _empty_space in 0..(x-i) { print!(" ") } for _left_side in 0..i { print!("L") } for _middle in i..i+1 { print!("M") } for _right_side in 0..i { print!("R") } println!(); thread::sleep(Duration::from_millis(120)); i += 1 } for _stem in 0..(x-1) { print!(" ") } println!("ШШШ"); } Try to colorize it using
[dependencies] colored = "2" 
Happy Holidays
