Problem Statement

A sparkline is a graph of successive values laid out horizontally where the height of the line is proportional to the values in succession.

Use the following series of Unicode characters to create a program that takes a series of numbers separated by one or more whitespace or comma characters and generates a sparkline-type bar graph of the values on a single line of output. The eight characters: '▁▂▃▄▅▆▇█' (Unicode values U+2581 through U+2588). Use your program to show sparklines for the following input, here on this page:

Let's start with the solution:

Step by Step solution about How to resolve the algorithm Sparkline in unicode step by step in the Rust programming language

Source code in the rust programming language

const BARS: &'static str = "▁▂▃▄▅▆▇█";

fn print_sparkline(s: &str){
    let v = BARS.chars().collect::<Vec<char>>();
    let line: String = s.replace(",", " ").split(" ")
                            .filter(|x| !x.is_empty())
                            .map(|x| v[x.parse::<f64>().unwrap().ceil() as usize - 1])
                            .collect();
    println!("{:?}", line);
}

fn main(){
    let s1 = "1 2 3 4 5 6 7 8 7 6 5 4 3 2 1";
    print_sparkline(s1);
    let s2 = "1.5, 0.5 3.5, 2.5 5.5, 4.5 7.5, 6.5";
    print_sparkline(s2);
}
