## tic_tac_toe
### Instructions
You must create some functions for a tic-tac-toe checker.
Create a function named `tic_tac_toe`, which receives a tic-tac-toe table. It should return the appropriate string: `"player O won"`, `"player X won"` or `"tie"`.
Also create the following functions, which each accept a player and a table. These functions should return `true` if the player has completed one of the diagonals, rows or columns:
### Expected functions
```rust
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 `tic_tac_toe`. You'll need to test the other functions yourself. But they'll probably be useful for implementing your `tic_tac_toe` checker.
```rust
use tic_tac_toe::*;
fn main() {
println!(
"{:?}",
tic_tac_toe(vec![
vec!["O", "X", "O"],
4 years ago
vec!["O", "O", "X"],
vec!["X", "#", "X"]
])
);
println!(
"{:?}",
tic_tac_toe(vec![
vec!["X", "O", "O"],
vec!["X", "O", "O"],
vec!["#", "O", "X"]
])
);
let dig = vec![
vec!["O", "O", "X"],
vec!["O", "X", "O"],
vec!["X", "#", "X"]
];
println!("{:?}",tic_tac_toe(dig));
}
```
And its output
```console
$ cargo run
"tie"
"player O won"
"player X won"
$
```
