How to check whether a sentence is palindrome in Rust

Answer 1

use regex::Regex;

fn is_sentence_palindrome(str: &str) -> bool {
    // Change the string into lowercase and remove all non-alphanumeric characters
    let re = Regex::new(r"[^a-zA-Z0-9]").unwrap();
    let cleaned_str = re.replace_all(&str.to_lowercase(), "").to_string();
        
    cleaned_str == cleaned_str.chars().rev().collect::<String>()
}

fn main() {
    println!("{}", if is_sentence_palindrome("Top step's pup's pet spot.") { "yes" } else { "no" });
}
