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 .

Input

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).

Output

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.
