## 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} |
||||||
|
