You are given positive integers $N$ and $M$.
How many sequences $a$ of length $N$ consisting of positive integers satisfy $a_1 \times a_2 \times ... \times a_N = M$? Find the count modulo $10^9+7$.
Here, two sequences $a'$ and $a''$ are considered different when there exists some $i$ such that $a_i' \neq a_i''$.
Input is given from Standard Input in the following format:
$N$ $M$
Print the number of the sequences consisting of positive integers that satisfy the condition, modulo $10^9 + 7$.

Four sequences satisfy the condition: $\{a_1, a_2\} = \{1, 6\}, \{2, 3\}, \{3, 2\}$ and $\{6, 1\}$.
