Curious about which audiences you should be targeting, you have gathered data about \(N\:(1 \le N \le 3 \cdot 10^5)\) different viewers. Specifically, you know the ages \(x_i\:(1 \le x_i \le 10^9)\) of every single person that has watched your video.

Given \(Q\:(1 \le Q \le 3 \cdot 10^5)\) different queries, how many people between the ages of a and b inclusive (1 \le a, b \le 10^9) have watched your video?

Input Specification

The first line of input contains an integer N.

The second line of input contains N space-separated integers x_i.

The third line of input contains an integer Q.

The next Q lines of input each contain 2 space-separated integers a and b (a \le b).

Output Specification

For each query, output the total number of viewers between the ages of a and b inclusive.
