Tavas is a cheerleader in the new sports competition named "Pashmaks".

This competition consists of two part: swimming and then running. People will immediately start running $*R*$ meters after they finished swimming exactly $*S*$ meters. A winner is a such person that nobody else finishes running before him/her (there may be more than one winner).
Before the match starts, Tavas knows that there are $*n*$ competitors registered for the match. Also, he knows that $*i*$-th person's swimming speed is $*s*_{*i*}$ meters per second and his/her running speed is $*r*_{*i*}$ meters per second. Unfortunately, he doesn't know the values of $*R*$ and $*S*$, but he knows that they are real numbers greater than $0$.
As a cheerleader, Tavas wants to know who to cheer up. So, he wants to know all people that might win. We consider a competitor might win if and only if there are some values of $*R*$ and $*S*$ such that with these values, (s)he will be a winner.
Tavas isn't really familiar with programming, so he asked you to help him.
Input
The first line of input contains a single integer $*n*$ ($1 ≤ *n* ≤ 2 × 10^{5}$).
The next $*n*$ lines contain the details of competitors. $*i*$-th line contains two integers $*s*_{*i*}$ and $*r*_{*i*}$ ($1 ≤ *s*_{*i*}, *r*_{*i*} ≤ 10^{4}$).
Output
In the first and the only line of output, print a sequence of numbers of possible winners in increasing order.
