// You will have to replace `part00` by `part01` in the `main` function in
// `main.rs` to run this code.
-// **Exercise**: Write a funtion `vec_avg` that computes the average value of a `Vec<i32>`.
+// **Exercise 01.1**: Write a funtion `vec_avg` that computes the average value of a `Vec<i32>`.
//
// *Hint*: `vec.len()` returns the length of a vector `vec`.
