# Files from RERSchallenge, category "Sequential Reachability Problems"
# Note that we exclude from this benchmark all files that fall in the
# category "Sequential Reachability Problems/data structures, hard" since
# they require complex array manipulation that are not yet supported by
# the Go2Pins tool.
