GSS5  Can you answer these queries V
You are given a sequence A[1], A[2], ..., A[N] . ( A[i] <= 10000 , 1 <= N <= 10000 ). A query is defined as follows: Query(x1,y1,x2,y2) = Max { A[i]+A[i+1]+...+A[j] ; x1 <= i <= y1 , x2 <= j <= y2 and x1 <= x2 , y1 <= y2 }. Given M queries (1 <= M <= 10000), your program must output the results of these queries.
Input
The first line of the input consist of the number of tests cases <= 5. Each case consist of the integer N and the sequence A. Then the integer M. M lines follow, contains 4 numbers x1, y1, x2 y2.
Output
Your program should output the results of the M queries for each test case, one query per line.
Example
Input: 2 6 3 2 1 4 5 2 2 1 1 2 3 1 3 2 5 1 1 1 1 1 1 1 Output: 2 3 1

no need to use scanf and printf, if you are using the "data structure" neatly ;)

Maximum N for some test cases is greater than 10^4. I was using 10^4 as maximum N but I was getting a SIGSEV. Got AC with 10^5 max N. Please fix either the statement or the test cases. Thanks for the problem!

Beautiful problem. Solve GSS1 first and then this will be easy
