standard outputLet's consider a table consisting of *n* rows and *n* columns. The cell located at the intersection of *i*-th row and *j*-th column contains number *i* × *j*. The rows and columns are numbered starting from 1.

You are given a positive integer *x*. Your task is to count the number of cells in a table that contain number *x*.

Input

The single line contains numbers *n* and *x* (1 ≤ *n* ≤ 10^{5}, 1 ≤ *x* ≤ 10^{9}) — the size of the table and the number that we are looking for in the table.

Output

Print a single number: the number of times *x* occurs in the table.
