Let'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.

Note

A table for the second sample test is given below. The occurrences of number $12$ are marked bold.
