how to create a string of n characters rust

To create a string of n characters in Rust, you can use the repeat method of the String type. Here's an example:

fn main() {
    let n = 5; // Replace 5 with the desired length of the string
    let s = "x".repeat(n);
    println!("{}", s);
}

This will create a string consisting of n number of characters, in this case, x. You can replace 5 with the desired length of the string. The resulting string will be printed to the console.
