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.

is this unsolvable using Java?
I am getting TLE even by using BufferedReader and PrintWriter for I/O

Nice problem. Finally AC :)

Very Weak test cases
first 8 cases are useless
my misunderstood range max query solution passes them

This is what we call a classical question..!!:)

Guys when submitting the code click "choose the file" not copy paste the code
Wasted my 4 hours :(

Are the given numbers sorted?

mishra10: 2017-06-10 05:27:34

Those of you getting W.A on test case 9 return negative number smaller than -15007 when there is no overlap..Hope this will help you to get AC.

use scanf() printf()

Getting TLE with whatsoever optimization in java. My solution has complexity of O(n+mlogn).
I am using fast read as well. Is there better solution than this time complexity?

First segtree problem, first time AC, feeling confident <3
