<p class="Body">If you provide an initial value, <code>reduce</code> starts by applying the given function to the initial value and the first element of the sequence rather than the first two elements of the sequence.</p>
<p class="Body">One detail to note is that, in these examples, <code>reduce</code> takes a collection of elements, <code>[1 2 3 4]</code>, and returns a single number. Although programmers often use <code>reduce</code> this way, you can also use <code>reduce</code> to return an even larger collection than the one you started with, as we’re trying to do with <code>symmetrize</code><code>-body-parts</code>. <code>reduce</code> abstracts the task “process a collection and build a result,” which is agnostic about the type of result returned. To further understand how <code>reduce</code> works, here’s one way that you could implement it:</p>
