RPLN  Negative Score
Orianna is a great swimmer and she's going to a swimming competition this month and needs your help as she is highly paranoic about the results of the competition.
The competition consists in some sort of evaluations, every judge makes a score and, based on that score and the score of other contestants she will get a score belonging to her results, those scores are final, meaning that will not change in the competition.
Orianna requires this solution with urgency, she is getting evaluated on a lot of ways and she is very worried about her results, so she wants to know what is the worst score from an evaluation A to other evaluation B inclusive.
Input
The first line of the test data will start with an integer T representing the T test cases, then, T cases will follow, each of the cases starts with two integers N and Q, denoting the number of evaluations Orianna had, then, N integers will follow denoting the score on each evaluation, after that, Q queries will begin, each query consist on two integers A and B.
Output
You must output the string “Scenario #i:“, a blank line and then the result of each query, remember, Orianna is interested on the worst score from evaluation A to evaluation B inclusive.
Example
Input: 2 5 3 1 2 3 4 5 1 5 1 3 2 4 5 3 1 2 4 3 5 1 5 1 3 2 4 Output: Scenario #1: 1 1 2 Scenario #2: 5 4 4
Constraints
 1 <= T <= 100
Small input (30%):
 1 <= N <= 1,000
 1 <= Q <= 1,000
 10^9 <= Ni <= 10^9
 1 <= A <= B <= N
Large input (70%):
 1 <= N <= 100,000
 1 <= Q <= 100,000
 10^9 <= Ni <= 10^9
 1 <= A <= B <= N
Solutions rejudged due to weak test cases.

use fast i/p o/p

use scanf, printf

use segment tree and assume large input as 1<=N<=10^6(for those who get SIGSEGV error at testcase 9). Last edit: 20160930 23:22:56

first segment tree question.... :)

So segment tree and fast i/o gives me 0.78s, Any idea on how to reduce this time?

just use an unordered_map for the segtree, and ios::sync_with_stdio(0) for fast i/o

really good problem...

Took all array sizes in 10^5,got AC(1.22s) using sparse table and using scanf and printf.

Solved using RMQ Sparse Table.
