## closures
|
||
|
|
|
||
|
|
### Instructions
|
||
|
|
|
||
|
|
Using closures and iterators create a function, `first_fifty_even_square` that returns the first 50
|
||
|
|
|
||
|
|
### Expected Functions
|
||
|
|
|
||
|
|
```rust
|
||
|
|
fn first_fifty_even_square() -> Vec<i32> {
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
### Usage
|
||
|
|
|
||
|
|
Here is a program to test your function.
|
||
|
|
|
||
|
|
```rust
|
||
|
|
fn main() {
|
||
|
|
println!("Hello, world!");
|
||
|
|
let v1 = first_fifty_even_square();
|
||
|
|
|
||
|
|
println!("All elements in {:?}, len = {}", v1, v1.len());
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
And its output
|
||
|
|
|
||
|
|
```console
|
||
|
|
student@ubuntu:~/[[ROOT]]/test$ cargo run
|
||
|
|
All elements in [4, 16, 36, ..., 10000], len = 50
|
||
|
|
student@ubuntu:~/[[ROOT]]/test$
|
||
|
|
```
