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

how to solve it ussing DSU by youssifgamal ?? too difficulty
2022-08-18 03:31:44
how could we solve it using DSU?

+ Sprase table (0,12s, 11M): <snip>
+ Segment tree (0,13s, 11M): <snip>
[Simes]: No thanks, we don't want links to code.

Also possible to solve using disjoint set union (https://cp-algorithms.com/data_structures/disjoint_set_union.html#arpa)

good question

Algo - Segment tree
Time : 0.07 s
Memory : 5.4 M

Much efficient with this algo, for both, time & memory

Yeah exactly Errichto's video on sparse table is excellent. Done with sparse table.

Solved using Square Root Decomposition, Segment tree and Sparse Table.
