GSS1  Can you answer these queries I
You are given a sequence A[1], A[2], ..., A[N] . ( A[i] ≤ 15007 , 1 ≤ N ≤ 50000 ). A query is defined as follows:
Query(x,y) = Max { a[i]+a[i+1]+...+a[j] ; x ≤ i ≤ j ≤ y }.
Given M queries, your program must output the results of these queries.
Input
 The first line of the input file contains the integer N.
 In the second line, N numbers follow.
 The third line contains the integer M.
 M lines follow, where line i contains 2 numbers xi and yi.
Output

Your program should output the results of the M queries, one query per line.
Example
Input: 3 1 2 3 1 1 2 Output: 2

used kadane algo for worst case scenario complexity is O(n*M), but TLE is the verdict !

test cases are pretty weak.. I got 3 of my solutions passed by introducing several bugs :p .. so guys, even if your solution passes the test cases, make sure your algorithm and/or implementation is actually correct.

Except for fast I/O don't look for anything , u can solve it .... :)

without range of M how can we compute the complexity for this problem?
