algorithm first requires the receiving party to issue a duplicate acknowledgment every time a sequence of messages is received (in order for the sender to know earlier that the message segment did not reach the other) and not wait for the sender to confirm the data.After receiving the M1 and M2, the receivers were given confirmation. Now assume that the receiver did not receive M3 but then received the M4. Obviously, the receiver cannot confirm the M4, because M4 is the received out-of-sequence

UESTC Department Canteen's rice card has a very strange design, that is, before the purchase to determine the balance. If the remaining amount on the card is greater than or equal to 5 yuan before the purchase of an item, the purchase must be successful (even if the balance is negative on the card after purchase), it cannot be purchased (even if the amount is sufficient). So we all want to try to keep the balance on the card to the minimum.One day, the canteen has n vegetables for sale, each veg
