Up You Go

Arya is taking part in a game of throwing marbles upwards. There are $n$ participants in this game in total, where Arya is the participant with label $1$. Each participant is given a marble and initially each of the marbles are held at ground level (height $0$). Each participant $x$ throws his marble straight upwards at time $s_x$ with initial velocity $u_x$ and it drops back on the ground after some time.

The marble will follow basic rules of physics while travelling in the air. So if a marble hasn't yet dropped back on the ground and $t$ time units have passed since it was thrown with initial velocity $u$, its current velocity $v$ and current height $h$ can be expressed as follows:

Here, $g=10$.

You have to answer $q$ queries, where you will be given an integer $T$ in each query.

For each query, count how many marbles have a strictly greater height than Arya's marble at time $T$.

Input

First line of the input contains two space-separated integers $n$ and $q$, denoting the number of participants and the number of queries.

Next $n$ lines each contains two integers $s_x$ and $u_x$, denoting when participant $x$ threw the marble and its initial velocity.

Next $q$ lines each contains one integer $T$, denoting the query time.

$1 \le n, q \le 10^5$

$1 \le u_x \le 10^8$

$0 \le s_x, T \le 10^8$

Output

For each query, output a single line containing one single integer denoting the number of marbles with a strictly greater height than Arya's marble at the query time.
