What clients have been sent to a crematorium ???

   2 2

2: 1 d
3: 1 d
4: 1 d
5: 300 d
   500 v 2
6: 1001 d
7: 1002 d
8: 1002 d
9: 1003 v 3
10:1003 d
11:1003 d
   1236 v 2
   2032 v 2
12:2033 d

I think 5,6,11,12 (4 clients)

As far as I can judge, there is a misprint in the sample output. You
are right, the correct answer should be four. Thus, let us wait a
couple of days, until the consultation with the task author will be
possible, and he will answer for sure.

   1236 v 2
   2032 v 2
11:2033 d

I think:
First 2 clients in crematorium are 5 and 6.
Next 3 clients are 8,9,10 because client-neighbour 7 is added
recently.
Last client is 11 because client-neighbour 2 is visited recently.

Totally 6 clients are in the crematorium.‰

3 to clematory

It is said "the manager puts a new client on a used place only if all
the neighboring graves have not been visited for the last 100 days".
So for 2x2 "2032 v 2" means all graves can't be used for clients until
2133.
So last client must be in crematorium.
I tried your interpretation but got WA 0.01 sec‰
