Problem U
Multiplication Table

In an $N\times N$ multiplication table, how many times does a given number $M$ appear?

The multiplication table is a matrix where the value of the $i$’th row of the $j$’th column ($1$-indexed) has the value $i\times j$.

Input

The first and only line contains the integers $N$ ($1\le N\le {10}^{12}$) and $M$ ($1\le M\le {10}^{12}$).

Output

Output the number of times $M$ appears in the given multiplication table.

Scoring

Your solution will be tested on a set of test groups, each worth a number of points. To get the points for a test group you need to solve all test cases in the test group.

Explanation of sample 1

The number $24$ appears $4$ times as $6\times 4$, $8\times 3$ and the same products in reverse order.
