Harry is a Junior middle student. He is very interested in the story told by his mathematics teacher about the Yang Hui triangle in the class yesterday. After class he wrote the following numbers to show the triangle our ancestor studied.

He found many interesting things in the above triangle. It is symmetrical, and the first and the last numbers on each line is 1; there are exactly i numbers on the line i.

Then Harry studied the elements on every line deeply. Of course, his study is comprehensive.

Now he wanted to count the number of elements which are the multiple of 3 on each line. He found that the numbers of elements which are the multiple of 3 on line 2, 3, 4, 5, 6, 7, … are 0, 0, 2, 1, 0, 4, … So the numbers of elements which are not divided by 3 are 2, 3, 2, 4, 6, 3, …, respectively. But he also found that it was not an easy job to do so with the number of lines increasing. Furthermore, he is not satisfied with the research on the numbers divided only by 3. So he asked you, an erudite expert, to offer him help. Your kind help would be highly appreciated by him.

Since the result may be very large and rather difficult to compute, you only need to tell Harry the last four digits of the result.

There are multiple test cases in the input file. Each test case contains two numbers P and N, (P < 1000, N ≤ 10⁹), where P is a prime number and N is a positive decimal integer.

P = 0, N = 0 indicates the end of input file and should not be processed by your program.
