Problem:
Division of Big Integers

Given two integers $A$ and $B$, compute the quotient, $\frac{A}{B}$. Round down to the nearest decimal.

Input

Two integers $A$ and $B$ separated by a space character are given in a line.

Output

Print the quotient in a line.

Constraints

$-1 \times 10^{1000} \leq A, B \leq 10^{1000}$

$B \ne 0$

Solution in Python3 (judge verdict: Accepted)

s = input().split()
a = int(s[0])
b = int(s[1])
f = False
if a < 0 : 
    a = -a
    b = -b
if b < 0 :
    f = True
    b = -b
ans = a // b
if f : ans = -ans
print(ans)
