 In this challenge, you need to declare one mutable variable inside the function using the `let mut` keyword:
 
 - `text` with an initial value of `"hello"`
-- Print it to the console using the `println!` macro.
+- Print exactly `"Text is hello"` to the console using the `println!` macro.
 - Mutate the variable to `"bye"`.
-- Print the variable again to the console using the `println!` macro.
+- Print exactly `"Text is bye"` to the console using the `println!` macro.
 - Return the final value of the variable.
 
 ### Println! Macro

 The `println!` macro is used to print text to the console. It is similar to the `println` function in other programming languages. The `println!` macro is used to print formatted text to the console.
 
 ```rust
-println!("Hello, World!");
+let text = "hello";
+println!("Text is {}", text);
 ```
 
+The `{}` is a placeholder that will be replaced by the value of the variable `text`.
+
 ## Hints
 
 - Use the `let mut` keyword to declare a mutable variable.
 - Reassign the variable directly by using the `=` operator.
 - Ensure to return the final value of the variable from the function.
-- Use `println!` statements to debug and check the values during reassignment.
