Problem: A cubic lattice L in 3-dimensional euclidean space is a set of points defined in the following way: $$$L=\\{u ⋅ \vec r_1 + v ⋅ \vec r_2 + w ⋅ \vec r_3\}_{u, v, w ∈ \mathbb Z} Where \vec r_1, \vec r_2, \vec r_3 \in \mathbb{Z}^3$$$ are some integer vectors such that: 

  * \vec r_1, \vec r_2 and \vec r_3 are pairwise orthogonal: $$$\vec r_1 ⋅ \vec r_2 = \vec r_1 ⋅ \vec r_3 = \vec r_2 ⋅ \vec r_3 = 0 Where \vec a \cdot \vec b is a dot product of vectors \vec a and \vec b$$$. 
  * \vec r_1, \vec r_2 and \vec r_3 all have the same length: $$$|\vec r_1| = |\vec r_2| = |\vec r_3| = r$$$ 

You're given a set A=\{\vec a_1, \vec a_2, ..., \vec a_n\} of integer points, i-th point has coordinates a_i=(x_i;y_i;z_i). Let g_i=\gcd(x_i,y_i,z_i). It is guaranteed that \gcd(g_1,g_2,...,g_n)=1.

You have to find a cubic lattice L such that A ⊂ L and r is the maximum possible.

Input

First line contains single integer n (1 ≤ n ≤ 10^4) — the number of points in A.

The i-th of the following n lines contains integers x_i, y_i, z_i (0 < x_i^2 + y_i^2 + z_i^2 ≤ 10^{16}) — coordinates of the i-th point.

It is guaranteed that \gcd(g_1,g_2,...,g_n)=1 where g_i=\gcd(x_i,y_i,z_i).

Output

In first line output a single integer r^2, the square of maximum possible r.

In following 3 lines output coordinates of vectors \vec r_1, \vec r_2 and \vec r_3 respectively.

If there are multiple possible answers, output any.
