I can follow the sample I/O but I can see more than one algorithm that gives the same output. E.g. "optimistic packet passing/as-soon-as-possible" or "buffering full message re-assembly."

Could someone please explain the output for these test cases:

Code: Select all

My program (wrong) gives:

Code: Select all

Case 1: 0

Case 2: 0

Case 3: 4

Case 4: 4

Case 5: 10

Particularly, cases 3 and 5 I think are wrong but do not understand why.

I am processing in each packet in turn, passing a packet as soon as possible and passing all packets for a message in-order. As each packet is processed, I track the current buffer size (either increasing it if buffering the packet or decreasing it if passing previously buffered packets). My output is the high watermark buffer size after processing all the packets.

I'm reasonably confident my approach is completely, totally and utterly wrong (!) but cannot see why. Any clues?

Many thanks in advance for any help!

AC output for your input:

Code: Select all

Case 1: 0

Case 2: 0

Case 3: 2

Case 4: 4

Case 5: 7

On case 3:
1 1 2 pass
2 1 2 buff
1 3 4 pass
2 1 2 exits buff
2 3 4 pass

On case 5:
3 1 3 pass
1 4 6 buff
2 3 6 buff
3 4 6 pass
2 1 2 pass
2 3 6 exits buff
1 1 3 pass
1 4 6 exits buff

My code is AC 0.252 sec and considers all possible orderings of the messages passing the buffer. Remember that "Note that unlike actual buffering systems, the process for this problem can look ahead at all incoming packets to make its decisions."

Thank you very much Brian - I understand now.

How the answer for

Code: Select all

can be 6? For ordering "2 1 3" I'm getting 5.

Posted: **Sat May 19, 2018 8:32 pm**

the response from my AC code is "Case 1: 5"

the process (note that message_number is represented message_number-1 in this trace):
R #0 4 4 to buffer mem 1 (max 1)
R #1 3 4 to buffer mem 3 (max 3)
R #1 1 2 passed
e #1 3 4 buffer out mem:1
R #2 1 1 to buffer mem 2 (max 3)
R #0 1 3 to buffer mem 5 (max 5)
R #1 5 5 passed
e #0 1 3 buffer out mem:2
e #0 4 4 buffer out mem:1
R #2 4 5 to buffer mem 3 (max 5)
R #2 2 3 to buffer mem 5 (max 5)
R #0 5 5 passed
e #2 1 1 buffer out mem:4
e #2 2 3 buffer out mem:2
e #2 4 5 buffer out mem:0
>> max buff == 5

remember: "Note that unlike actual buﬀering systems, the process for this problem can look ahead at all incoming packets to make its decisions."
