## expected_variable
|
||
|
|
|
||
|
|
### Instructions
|
||
|
|
|
||
|
|
Create a function `expected_variable` that receives two strings: one to be evaluated and the other to be compared to (expected) and returns an Option. Every comparison should be case insensitive.
|
||
|
|
|
||
|
|
If the evaluated string is not in camel case or in snake case according to the `case` crate that you should use, `expected_variable` returns None.
|
||
|
|
Otherwise the evaluated string should be compared to the expected string using the `edit_distance` function that you did in one of the previous quests.
|
||
|
|
|
||
|
|
If the result of `edit_distance` has more than 50% of 'alikeness' to the expected string, considering the length of the expected string and the result of `edit_distance`, return that same percentage with a '%' symbol in front of the number.
|
||
|
|
Otherwise `expected_value` should return None.
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
```rs
|
||
|
|
fn main() {
|
||
|
|
println!(
|
||
|
|
"{} close to it",
|
||
|
|
expected_variable("On_Point", "on_point").unwrap()
|
||
|
|
);
|
||
|
|
println!(
|
||
|
|
"{} close to it",
|
||
|
|
expected_variable("soClose", "So_Close").unwrap()
|
||
|
|
);
|
||
|
|
println!(
|
||
|
|
"{} close to it",
|
||
|
|
expected_variable("something", "something_completely_different").unwrap()
|
||
|
|
);
|
||
|
|
println!(
|
||
|
|
"{} close to it",
|
||
|
|
expected_variable("BenedictCumberbatch", "BeneficialCucumbersnatch").unwrap()
|
||
|
|
);
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
And its output:
|
||
|
|
|
||
|
|
```sh
|
||
|
|
$ cargo run
|
||
|
|
