Thank you so much!

If my thinking is approximately right ,you can just give me some examples that my program would return wrong answers.

I think I could try to find the mistakes by myself.

Code: Select all

...

(Sorry,I am not good at speaking or writing English...)

Your code looks correct. But you have some wrong in your output.

1. Don't print a space after any line. The sample output is

Code: Select all

2.1.3.4

here '.' represents a space.
2. The outputs of two consecutive cases will be separated by a blank line. But your are printing a blank line after every case.

Hope these help.

I am sorry, I don't completely understand your second point.(I know that's what the problem says.)

But I changed my code, I hope I guess right.

Code: Select all

. . .

Check the set carefully.

Input:

Code: Select all

Output:

Code: Select all

2 1 3 4^
^
2 1 3 4^

Where '^' represents a newline character. Hope these help.

I am sorry to trouble you a lot.

But I still get W.A.

I am now wondering if my answer is really wrong.

Code: Select all

Your code is correct now! Just read the description again. Your code can overflow. So, change the following parts.

Code: Select all

long long paymoney(int);
...
long long flag,newflag;
...
long long paymoney(int a) 
{ long long i,sumdays=0,sum;
...
}

Hope these help.

Read the i/o specifications again. Your code can't pass the samples.

The input begins with a single positive integer on a line by itself indicating the number of the cases following, each of them as described below. This line is followed by a blank line, and there is also a blank line between two consecutive inputs.

Yeah, I wasn't sure if it is input or just a newline. Thx but still can't pass (I tried this option even before)
