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.

Note

Let's consider all samples:
