-// In this exercise, we are given a `Vec` of `u32` called `numbers` with values
-// ranging from 0 to 99. We would like to use this set of numbers within 8
-// different threads simultaneously. Each thread is going to get the sum of
-// every eighth value with an offset.
-//
-// The first thread (offset 0), will sum 0, 8, 16, …
-// The second thread (offset 1), will sum 1, 9, 17, …
-// The third thread (offset 2), will sum 2, 10, 18, …
-// …
-// The eighth thread (offset 7), will sum 7, 15, 23, …
-//
-// Each thread should own a reference-counting pointer to the vector of
-// numbers. But `Rc` isn't thread-safe. Therefore, we need to use `Arc`.
-//
-// Don't get distracted by how threads are spawned and joined. We will practice
-// that later in the exercises about threads.
-
-// Don't change the lines below.
