list_math

This crate provides functions for performing basic mathematical operations on lists in Rust.

Installation

Add the following line to your Cargo.toml file:

[dependencies]
list_math = "0.1.0"

Then run cargo build to install the crate.

Usage

largest function

The largest function finds the largest element in a list of isize values.

use list_math::largest;

fn main() {
let numbers = vec![ 3 , 10 , - 1 , 5 ];
let biggest = largest(&numbers);
println!("The largest number is: {}", biggest);
}

This code will print:

The largest number is: 10

smallest function

The smallest function finds the smallest element in a list of isize values.

use list_math::smallest;

fn main() {
let numbers = vec![ 3 , 10 , - 1 , 5 ];
let biggest = smallest(&numbers);
println!("The smallest number is: {}", biggest);
}

This code will print:

The smallest number is: -1

AverageList struct

The AverageList struct helps you keep track of a running average of i32 values.

use list_math::AverageList;

fn main() {
let mut avg_list = AverageList::new();
avg_list.add( 2 );
avg_list.add( 8 );
avg_list.add( 4 );
println!("Current average: {}", avg_list.average()); // Output: 4.
avg_list.remove(); // Removes last element (4)
println!("Average after removal: {}", avg_list.average()); // Output: 5.
}

This code will print:

Current average: 4.
Average after removal: 5.

Methods: ● new: Creates a new AverageList with an initial average of 0. ● add(value): Adds a new value to the list and updates the average. ● remove:Removes the last added value from the list and updates the average (returns None if the list is empty). ● average: Returns the current average as a f64.
