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.


  • 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.


Your program should output the results of the M queries, one query per line.

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.

test case 9 run time error(python 3.5). any suggestions?

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

use long long int :)

use scanf and printf for AC........
using sync_with_stdio(false) will also give tle

no constraints for queries?

badia question hai madarjaat

This problem can also be solved by dsu with complexity O(n alpha(n))

Assume 1 based indexing for the input array as well as the queries. So the input array will be from [1...n]. Cost me a couple of WA! :(
