Hi Gerry,
PLAN (BEFORE START):
THERE ARE 40 BLOCKS AVAILABLE AT THE BEGINNING.
WE NEED 38 BRIDGE-BLOCKS IF ALL BLOCKS ARE FREE.
THEREFORE, WE MAY LOSE TWO BLOCKS.
YOU WROTE THAT YOU NEED ONE BLOCK AT E-4. YES!
THAT'S THE ONE WASTED. THE OTHER ONE MUST BE
USEFUL TO AVOID DEADLOCK.
(See the answer to your questions below.)
Bye,
Suyono
