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

AC with Sparse Table.

This is the problem where sparse table shines! (0.06s)
others possible ds -> segtree, BIT, mo's

@nikhil_33 the range is already in 0 index format, u must be decrementing , also increment l and r for 0 index and later decrement.

simple using sqrt decomposition!

i am getting tle using seg tree..

I am using sparse table and getting wrong answer after 5th case. Can anyone help me?

using mo's algo its become very easy ..

pure segment tree ... very nice problem.

not sure why but ,it even accepted my naive's solution, which I guessed to show TLE, xp
