Consider a two-dimensional plane. There are N poles standing parallel to y-axis. The ith pole has height Hi and is between y = 0 and y = Hi and at position Xi. The gravity acts along negative y-axis and its value is 10. Q projectiles are launched from origin with the jth projectile launched at an angle Aj and with speed Sj. For each projectile, print the index of pole that the projectile hits.

The poles in input are arranged in increasing order of Xi. If a projectile doesn't hit any pole, print -1. Indices of pole starts from 1. The angle is given in degrees and all other units follow SI.

Constraints

1 <= N <= 10^5

1 <= Q <= 10^5

1 <= Xi <= 10^9

1 <= Sj <= 10^9

1 <= Aj <= 89

1 <= Hi <= 100

Input

All values in input are integers.

The first line contains N.

The next N lines containes two space separated integers Xi and Hi. The Xis' are in increasing order and unique.

The next line contains Q.

The next Q line contains two space separated integers Aj and Sj.

Output

Print Q lines each containing the pole index hit by the jth projectile. If a projectile doesn't hit any pole, then print -1.
