RMQSQ - Range Minimum Query
You are given a list of N numbers and Q queries. Each query is specified by two numbers i 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 (Q <= 10,000). The next Q lines each contain two numbers i and j 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

This is the problem where sparse table shines! (0.06s)

@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. |

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