Struct lib::ZeroEquation

pub struct ZeroEquation { /* private fields */ }

ZeroEquation is an equation with a list of values on one side and a solution on the other. Similar to Equation, but with a list of values (in a Vec) that will add up to the solution (or be subtracted if the number is negative). Sol is set to 0 and values can be moved to the solution side of the equation with move_to_sol().

Example

use numbers_rus::ZeroEquation;
let mut equation = ZeroEquation::new(vec![1, 2, 3]);
assert_eq!(equation.get_sol(), 0);

Implementations

impl ZeroEquation

pub fn new(values: Vec<i128>) -> ZeroEquation

pub fn get_values(&self) -> Vec<i128>

returns all the values in the equation

pub fn get_value(&self, index: usize) -> i128

returns the value at the given index

pub fn add_value(&mut self, value: i128)

adds a single value to the list of values

pub fn remove_value(&mut self, index: usize)

removes a single value from the list of values

pub fn get_sol(&self) -> i128

returns the solution

pub fn move_to_sol(&mut self, index: usize) -> i128

pub fn is_valid(&mut self) -> bool

returns true if the values add up to the solution

pub fn get_error(&mut self) -> i128

returns the difference between the solution and the sum of the values if the values do not add up to the solution
