You are given two polynomials:
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).
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.
