SP1043 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.
