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.

USE fast input reader for ip
USe stringbiulder to store op and print all at once at the end
And maybe some optimizations inside

Extremely strict TL. Same idea using struct passed, but using vector gets TLE :/

The problem requires fast input/output, I had a TLE even with sync_with_stdio(false) and tie(0)

To think the problem designer could have come this far in thinking ahead !!!.....Finally solved it...

This problem really taught me a lot
though one simple mistake caused me to submit 12 WAs :/

If the aeeay is 1-inexed how is the output of the sample 2 ?
