## simple_hash |
||||
|
||||
### Instructions |
||||
|
||||
- Create the function `contain` that checks a `HashMap` to see if it contains the given key. |
||||
|
||||
- Create the function `remove` that removes a given key from the `HashMap`. |
||||
|
||||
### Expected Functions |
||||
|
||||
```rust |
||||
fn contain(h: HashMap<&str, i32>, s: &str) -> bool { |
||||
} |
||||
|
||||
fn remove(mut h: HashMap<&str, i32>, s: &str) { |
||||
} |
||||
``` |
||||
|
||||
### Usage |
||||
|
||||
Here is a program to test your function. |
||||
|
||||
```rust |
||||
use std::collections::HashMap; |
||||
|
||||
fn main() { |
||||
let mut hash: HashMap<&str, i32> = HashMap::new(); |
||||
hash.insert("Daniel", 122); |
||||
hash.insert("Ashley", 333); |
||||
hash.insert("Katie", 334); |
||||
hash.insert("Robert", 14); |
||||
|
||||
println!( |
||||
"Does the HashMap contains the name Roman? => {}", |
||||
contain(hash.clone(), "Roman") |
||||
); |
||||
println!( |
||||
"Does the HashMap contains the name Katie? => {}", |
||||
contain(hash.clone(), "Katie") |
||||
); |
||||
println!("Removing Robert {:?}", remove(hash.clone(), "Robert")); |
||||
println!("Hash {:?}", hash); |
||||
} |
||||
``` |
||||
|
||||
And its output |
||||
|
||||
```console |
||||
student@ubuntu:~/[[ROOT]]/test$ cargo run |
||||
Does the HashMap contains the name Roman? => false |
||||
Does the HashMap contains the name Katie? => true |
||||
Removing Robert () |
||||
Hash {"Daniel": 122, "Ashley": 333, "Robert": 14, "Katie": 334} |
||||
student@ubuntu:~/[[ROOT]]/test$ |
||||
``` |
