## get_products
|
||
|
|
|
||
|
|
### Instructions
|
||
|
|
|
||
|
|
Create a function `get_products` that takes a vector of integers, and returns a vector of the products
|
||
|
|
of each index. For this exercise to be correct you will have to return the product of every index
|
||
|
|
except the current one.

### Expected functions

### Usage
|
||
|
|
|
||

||
|
|
|
||

|
|
fn main() {
|
||
|
|
let arr: Vec<usize> = vec![1, 7, 3, 4];
|
||
|
|
let output = get_products(arr);
|
||
|
|
println!("{:?}", output);
|
||
|
|
}
|
||
|
|
```
|
||
|

|
|
And its output
