fn starts_with_any(string: &str, substrings: &[&str]) -> bool {
    for &substring in substrings {
        // Use the starts_with method to check if the string starts with the substring
        if string.starts_with(substring) {
            return true;
        }
    }
    false // Return false if no substring matches
}

fn main() {
    let string = "abcdefg";

    // Array of substrings
    let substrings = ["xy", "poq", "mnop", "abc", "rsuvw"];

    // Check if the string starts with any substring from the array
    if starts_with_any(string, &substrings) {
        println!("The string starts with a substring from the array.");
    } else {
        println!("The string does not start with any substring from the array.");
    }
}


      
/*
run:

The string starts with a substring from the array.
     
*/
