tic_tac_toe

Instructions

You must create a tic tac toe checker.

Create the following functions:

• tic_tac_toe which receives:
  • a table of vectors (Vec<Vec<&str>>).
  • It should return a String player O won or player X won or Tie.
• diagonals which will receive:
  • a player and a table.
  • It should return a boolean, this must return true if all the diagonals are completed by the player.
• horizontal which will receive:
  • a player and a table.
  • It should return a boolean, this must return true if one of the horizontal lines are completed by the player.
• vertical which will receive:
  • a player and a table.
  • It should return a boolean, this must return true if one of the vertical lines are completed by the player.

Notions

• references and borrowing

Expected Functions

pub fn tic_tac_toe(table: Vec<Vec<&str>>) -> String {
}

pub fn diagonals(player: &str, table: &Vec<Vec<&str>>) -> bool {
}

pub fn horizontal(player: &str, table: &Vec<Vec<&str>>) -> bool {
}

pub fn vertical(player: &str, table: &Vec<Vec<&str>>) -> bool {
}

Usage

Here is a program to test your function

use tic_tac_toe::*;

fn main() {
    println!(
        "{:?}",
        tic_tac_toe(vec![
            vec!["O", "X", "O"],
            vec!["O", "P", "X"],
            vec!["X", "#", "X"]
        ])
    );
    // "Tie"
    println!(
        "{:?}",
        tic_tac_toe(vec![
            vec!["X", "O", "O"],
            vec!["X", "O", "O"],
            vec!["#", "O", "X"]
        ])
    );
    // "player O won"

    let dig = vec![
            vec!["O", "O", "X"],
            vec!["O", "X", "O"],
            vec!["X", "#", "X"]
        ];

    println!("{:?}",tic_tac_toe(dig));
    // "player X won"
}

And its output
