How to replace multiple spaces in a string with a single space between words in Rust

Answer 1

fn replace_multiple_spaces(s: &str) -> String {
    // Replace multiple spaces with a single space using regex
    let re = regex::Regex::new(r"\s+").unwrap();
    let result = re.replace_all(s, " ");

    // Trim leading and trailing spaces
    result.trim().to_string()
}

fn main() {
    let s = "   This   is    a   string   with   multiple    spaces   ";
    let output = replace_multiple_spaces(s);

    println!("\"{}\"", output);
}


      
/*
run:

"This is a string with multiple spaces"
     
*/
