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 $$\lim_{x \to +\infty} \frac{P(x)}{Q(x)}$$.

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): 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).

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 $$\lim_{x \to +\infty} \frac{P(x)}{Q(x)}$$, in the format "p/q" (without the quotes), where p is the — numerator, q (q > 0) is the denominator of the fraction.

Let's consider all samples:

1. $$\lim_{x \to +\infty} \frac{x^2+x+1}{2x+5} = +\infty$$
2. $$\lim_{x \to +\infty} \frac{-x+3}{2} = -\infty$$
3. $$\lim_{x \to +\infty} \frac{1}{x} = 0$$
4. $$\lim_{x \to +\infty} \frac{2x^2+x+6}{4x^2+5x-7} = \frac{1}{2}$$
5. $$\lim_{x \to +\infty} \frac{9x}{-5x+2} = -\frac{9}{5}$$
