ownership

Instruction

  • Create a function that takes ownership of a string and returns the first sub-word in it

  • It should work for camelCase as well as snake_case

Expected Function

pub fn first_subword(mut s: String) -> String {
}

Usage

Here is a program to test your function

fn main() {
	let s1 = String::from("helloWorld");
	let s2 = String::from("snake_case");
	let s3 = String::from("CamelCase");
	let s4 = String::from("just");

	println!("first_subword({}) = {}", s1.clone(), first_subword(s1)); 
	println!("first_subword({}) = {}", s2.clone(), first_subword(s2));
	println!("first_subword({}) = {}", s3.clone(), first_subword(s3));
	println!("first_subword({}) = {}", s4.clone(), first_subword(s4));
}

And its output

student@ubuntu:~/[[ROOT]]/test$ cargo run
first_subword(helloWorld) = hello
first_subword(snake_case) = snake
first_subword(CamelCase) = Camel
first_subword(just) = just
