In hw 3 q2, it is stated that for sanity check, for both a=0 and a=1 the result should be 2.
but I don't understand it, if a=1 then the attack will end after 1 turn because it is guaranteed that the attacker will create the next block and win,
If a=0 then it is guaranteed that after each block, the attacker will be 1 more block behind the main chain, so if we are currently tied, it will take us exactly 3 blocks created until we are 3 block behind the main chain and will stop the attack.
