Hello,
Can you please explain the technical details on how the original list is restored?

When you reversed second half using
headSecondHalf = reverse(slow);

Now after the matching since you stored the headSecondHalf head in copyHeadSecondHalf
with reverse(copyHeadSecondHalf) it will reverse back.
