## hashing
|
||
|
|
||
|
### Instructions
|
||
|
|
||
|
Given a list of integers (Vec<i32>) write three functions
|
||
|
|
||
|
Write a function called `mean` that calculates the `mean` (the average value) of all the values in the list
|
||
|
|
||
|
Write a function called `median` that calculates the `median` (for a sorted list is the value in the middle)
|
||
|
|
||
|
Write a function called `mode` that calculates the mode (the value
|
||
|
that appears more often)
|
||
|
|
||
|
### Expected Functions
|
||
|
|
||
|
```rust
|
||
|
fn mean(list: &Vec<i32>) -> f64 {
|
||
|
}
|
||
|
|
||
|
fn median(list: &Vec<i32>) -> i32 {
|
||
|
}
|
||
|
|
||
|
fn mode(list: &Vec<i32>) -> i32 {
|
||
|
}
|
||
|
```
|
||
|
|
||
|
### Usage
|
||
|
|
||
|
Here is a program to test your function.
|
||
|
|
||
|
```rust
|
||
|
use hashing;
|
||
|
|
||
|
fn main() {
|
||
|
println!("Hello, world!");
|
||
|
let v = vec![4, 7, 5, 2, 5, 1, 3];
|
||
|
println!("mean {}", hashing::mean(&v));
|
||
|
println!("median {}", hashing::median(&v));
|
||
|
println!("mode {}", hashing::mode(&v));
|
||
|
}
|
||
|
```
|
||
|
|
||
|
And its output
|
||
|
|
||
|
```console
|
||
|
student@ubuntu:~/[[ROOT]]/test$ cargo run
|
||
|
mean 3.857142857142857
|
||
|
median 4
|
||
|
mode 5
|
||
|
student@ubuntu:~/[[ROOT]]/test$
|
||
|
```
