// You will have to replace `part00` by `part01` in the `main` function in
// `main.rs` to run this code.
-// **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`.
+// **Exercise 01.1**: Write a funtion `vec_sum` that computes the sum of all values of a `Vec<i32>`.
+
+// **Exercise 01.2**: Write a function `vec_print` that takes a vector and prints all its elements.
