## reverse_it
|
||
|
|
|
||
|
|
### Instructions
|
||
|
|
|
||
|
|
Create a function called `reverse_it` that takes a number and returns a string with the number backwards followed by the original number. If the number is negative you should
|
||
|
|
just add the char `-` to the beginning of the string.
|
||
|
|
|
||
|
|
### Expected Functions
|
||
|
|
|
||
|
|
```rust
|
||
|
|
fn reverse_it(v: i32) -> String {}
|
||
|
|
```
|
||
|
|
|
||
|
|
### Usage
|
||
|
|
|
||
|
|
Here is a program to test your function
|
||
|
|
|
||
|
|
```rust
|
||
|
|
fn main() {
|
||
|
|
println!("{}", reverse_it(123));
|
||
|
|
println!("{}", reverse_it(-123));
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
And its output
|
||
|
|
|

```console
|

student@ubuntu:~/[[ROOT]]/test$ cargo run
