Make the string a list of separatedd strings
In this task I want you to take a string with ascii text and split it into a list of strings with all the words from the original string separated by a string containing a separator. Also given to you. For example:
input: string:"Lorem ipsum dolor sit amet", separator: '_'
output: ["Lorem", "_", "ipsum", "_", "dolor", "_", "sit", "_", "amet"]
fn separate_strings(list: &str, separator: char) -> Vec<String> {
let mut res: Vec<String> = Vec::new();
let words: Vec<&str> = list.split(" ").collect();
let total = words.len();
for (index, word) in words.iter().enumerate() {
res.push(String::from(*word));
if index < total - 1 {
res.push(separator.to_string());
}
}
res
}// Add your tests here.
