MAXSUMSQ - Maximum Sum Sequences


Given an array A having n elements, let X be the maximum sum of any contiguous sequence in the array. How many contiguous sequences in A sum up to X?

Input

The first line contains T the number of test cases. There follow 2T lines, 2 for each test case. The first line contains the n, the number of elements in the array. The second line contains n space separated integers Ai.

Output

Output T lines, one for each test case. On each line, output two space separated integers; the maximum sequence sum, and the number of sequences which obtain this maximum sum.

Example

Input:
2
3
-1 -1 -1
4
2 0 -2 2 Output: -1 3
2 4

Constraints

1 <= T <= 35
1 <= n <= 100000
-1000 <= Ai <= 1000

Can be done in O(n) time and O(1) space without any casing :)

Nice Problem!!learned many new thngs

can somebody explain second test case . I think output should be : 2 3

Hi dear
i can :)
"2" , "2 0" , "2 0 -2 2 ", "2" !!!

will brute force work ?

<b>Finally AC</b> too many cases to handle, got a lot of WA *_*
