Limit
题意翻译
两个函数P(x)与Q(x)：
P(x)=a$_0$*x$^n$+a$_1$*x$^{n-1}$+……+a$_{n-1}$*x+a$_n$
和
Q(x)=b$_0$*x$^n$+b$_1$*x$^{n-1}$+……+b$_{n-1}$*x+b$_n$
当x趋近于无穷大时，P(x)/Q(x)收敛于a，而你要算的，便是这个a
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 .

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.
