## 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 one of 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.

### 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 function
```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"]
])
);
// "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
```console
student@ubuntu:~/[[ROOT]]/test$ cargo run
"Tie"
"player O won"
"player X won"
student@ubuntu:~/[[ROOT]]/test$
```
