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

@geek_lady take i=1 and j=1 (assuming 0-indexing in array) we get sum =2.
