题目描述

You are given two polynomials:

$P(x)=a_{0}·x^{n}+a_{1}·x^{n-1}+...+a_{n-1}·x+a_{n}$ and
$Q(x)=b_{0}·x^{m}+b_{1}·x^{m-1}+...+b_{m-1}·x+b_{m}$ .

Calculate limit .

输入格式

The first line contains two space-separated integers $n$ and $m$ ( $0<=n,m<=100$ ) — degrees of polynomials $P(x)$ and $Q(x)$ correspondingly.

The second line contains $n+1$ space-separated integers — the factors of polynomial $P(x)$ : $a_{0}$ , $a_{1}$ , ..., $a_{n-1}$ , $a_{n}$ $(-100<=a_{i}<=100,a_{0}≠0)$ .

The third line contains $m+1$ space-separated integers — the factors of polynomial $Q(x)$ : $b_{0}$ , $b_{1}$ , ..., $b_{m-1}$ , $b_{m}$ $(-100<=b_{i}<=100,b_{0}≠0)$ .

输出格式

If the limit equals $+∞$ , print "Infinity" (without quotes). If the limit equals $-∞$ , print "-Infinity" (without the quotes).

If the value of the limit equals zero, print "0/1" (without the quotes).

Otherwise, print an irreducible fraction — the value of limit , in the format "p/q" (without the quotes), where $p$ is the — numerator, $q$ (q>0) is the denominator of the fraction.
