let my_string = "HELLO WORLD";
let my_string_lowercase = my_string.to_lowercase();
println!("{}", my_string_lowercase);

• let my_string = "HELLO WORLD";: This line declares a variable my_string and assigns it the value of the string "HELLO WORLD".
• let my_string_lowercase = my_string.to_lowercase();: This line calls the to_lowercase() method on the my_string variable, and assigns the result to the my_string_lowercase variable.
• println!("{}", my_string_lowercase);: This line prints the value of the my_string_lowercase variable to the console.
