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

TL is very strict for JAVA.

pykay, probably blanklines somewhere in the input. You're wasting your time anyway, problems from this series have TL too tight for Python solution to pass.

I don't understand why I am getting a TLE, I am using scanf, printf, using bit manipulation for multiplication and division.
