Limit
Description
You are given two polynomials:
- P(x) = a0·xn + a1·xn - 1 + ... + an - 1·x + an and
- Q(x) = b0·xm + b1·xm - 1 + ... + bm - 1·x + bm.
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): a0, a1, ..., an - 1, an ( - 100 ≤ ai ≤ 100, a0 ≠ 0).
The third line contains m + 1 space-separated integers — the factors of polynomial Q(x): b0, b1, ..., bm - 1, bm ( - 100 ≤ bi ≤ 100, b0 ≠ 0).
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.
