3257 let llm_response = indoc! {r#"
3258 Sure, I can help you with that. Here's a step-by-step process:
3259
3260 <step>
3261 First, let's extract the greeting into a separate function:
3262
3263 ```rust
3264 fn greet() {
3265 println!("Hello, World!");
3266 }
3267
3268 fn main() {
3269 greet();
3270 }
3271 ```
3272 </step>
3273
3274 <step>
3275 Now, let's make the greeting customizable:
3276
3277 ```rust
3278 fn greet(name: &str) {
3279 println!("Hello, {}!", name);
3280 }
3281
3282 fn main() {
3283 greet("World");
3284 }
3285 ```
3286 </step>
3287
3288 These changes make the code more modular and flexible.
