Statement

Your program must calculate the value of limx ↦ ∞a₁x + a₂x² + …  + a_nxⁿb₁x + b₂x² + …  + b_nxⁿ.

All coefficients are integers, so the answer must be calculated exactly and presented in the form of irreducible fraction.

Input file format

Input file contains integer n followed first by n integers a₁ a₂… a_n and then by n integers b₁ b₂… b_n.

Output file format

Output file must contain two integers — nominator and denominator of the fraction. If the limit is zero, output integers 0 1. If the limit is infinity, output integers 1 0.

Constraints

1 ≤ n ≤ 100, 0 ≤ a_i, b_i ≤ 10⁹, ∑i (b_i + a_i) > 0
