Let's define a function $f(p)$ on a permutation $p$ as follows. Let $g_i$ be the greatest common divisor (GCD) of elements $p_1$, $p_2$, ..., $p_i$ (in other words, it is the GCD of the prefix of length $i$). Then $f(p)$ is the number of distinct elements among $g_1$, $g_2$, ..., $g_n$.
Let $f_{max}(n)$ be the maximum value of $f(p)$ among all permutations $p$ of integers $1$, $2$, ..., $n$.
Given an integers $n$, count the number of permutations $p$ of integers $1$, $2$, ..., $n$, such that $f(p)$ is equal to $f_{max}(n)$. Since the answer may be large, print the remainder of its division by $1000\,000\,007 = 10^9 + 7$.
Input
The only line contains the integer $n$ ($2 \le n \le 10^6$) — the length of the permutations.
Output
The only line should contain your answer modulo $10^9+7$.
Note
Consider the second example: these are the permutations of length $3$:
$[1,2,3]$,$f(p)=1$.$[1,3,2]$,$f(p)=1$.$[2,1,3]$,$f(p)=2$.$[2,3,1]$,$f(p)=2$.$[3,1,2]$,$f(p)=2$.$[3,2,1]$,$f(p)=2$.
The maximum value $f_{max}(3) = 2$, and there are $4$ permutations $p$ such that $f(p)=2$.
