RMQSQ - Range Minimum Query

You are given a list of numbers and queries. Each query is specified by two numbers and j; the answer to each query is the minimum number between the range [i, j] (inclusive).

Note: the query ranges are specified using 0-based indexing.

Input

The first line contains N, the number of integers in our list (N <= 100,000). The next line holds N numbers that are guaranteed to fit inside an integer. Following the list is a number (Q <= 10,000). The next Q lines each contain two numbers i and which specify a query you must answer (0 <= i, j <= N-1).

Output

For each query, output the answer to that query on its own line in the order the queries were made.

Example

Input:
3
1 4 1
2
1 1
1 2 Output: 4
1

Sparse Table makes your life easier !!!

AC in one go. Easy with segment tree.

Easy using segment tree. Easier Using Sparse Table:)

I tried many times using Segment tree but I am getting WA after the 5th case. Can anyone help me?

ac in one go python 3.5 just increase recursion limit by sys.setrecursionlimit(15000) and use segment tree

AC With Square Root Decomposition. Now Try With Segment Tree. And then will try with Sparse TAble.

ac 0.01s using segment tree

0.03 sec for sparse tree with log optimization :)
