I can't solve this problem. As I see, it's not so hard, but all my attempts to get AC failed

. Could anyone tell me, what's wrong with the problem?

Which years before doors are considered leap? Those like 4bd or those like 5bd? I am asking because for example, 5bd is 8 years before 4, which is a leap year.

I am trying to solve this problem, but I can't get ACC.
I hate this kind of problems, but would really like to solve this one.
(personaly, this is one of the most ugly problems I have ever seen)
Please, post some inputs and clarifications ( if you can think of any ) because I am doing something wrong...
Thank You!

Sorry, my solution is in Pascal and I currently have no compiler for it.

One, quite simple, way to test your program is to write two functions old_next(year,month,day) and new_next(year,period,month,week,day) that can be implemented as a series of nested if-else statements. You could internally represent the 'feast' days as period 3, or something like that.

Now have a program that writes old dates to a file called 'test.in' and new dates to a file called 'test.out'. Start the program off at old date (1600,1,1) and new date (-399,2,1,2,4), writing to the files and calling old_next() and new_next(), until you reach new date (5000,1,1).

Run your solution with 'test.in' as input and compare its output with 'test.out'.

EDIT: stubbscroll is right, 1600-01-01 is Bates-Sun-Second-4-399bd. I changed my posting accordingly.

Rio, I get a different output for line 5 with my AC program. Here's my output for your tests:

Thanks, little joey and stubbscroll.

I found the bug and got AC.
I was re-using functions witch I made for "602 What Day Is It?", and forgot to modify it.

I assumed, that leap years before doors are 4bd, 8bd, 12bd, ... and I got AC.
