This problem tests your mathematic knowledge and your programming ability very much. Your task is to calculate the number of different Minimum Spanning Trees (MSTs) of a special undirected unweighted graph. The graph has n nodes numbered from 1 to n, and there is an edge between node i (1<=i<=n) and node j (1<=j<=n) if and only if 0<|i-j|<=k.

### Input

Multiple test cases, the number of them(<=8) is given in the very first line.

Each test case contains one line with two space-separated numbers k(1<=k<=5) and n(1<=n<=1015).

### Output

For each test case you should output one line, the number of different MSTs of the corresponding graph modulo 65521.

### Example

```Input:
1
3 5

Output:
75

(hey i'm hinting you) Paul Draper: 2009-04-28 10:17:00 What trees are unique? Is 1-2-3 unique from 2-1-3?
