577_A. Multiplication Table
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 ≤ 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.

```python
import sys
n, x = map(int, sys.stdin.readline().split())
s = 0
for i in range(1, n + 1):
    if (x % i == 0 and x / i <= n):
        s += 1
print(s)
