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 numberi × 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 ≤ 105, 1 ≤ x ≤ 109) — 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.
