The Maximum Subarray

We define subsequence as any subset of an array. We define a subarray as a contiguous subsequence in an array.

Given an array, find the maximum possible sum among:

all nonempty subarrays.
all nonempty subsequences.

Print the two values as space-separated integers on one line.

Note that empty subarrays/subsequences should not be considered.

For example, given an array , the maximum subarray sum is comprised of element inidices and the sum is . The maximum subsequence sum is comprised of element indices and the sum is .

Function Description

Complete the maxSubarray function in the editor below. It should return an array of two integers: the maximum subarray sum and the maximum subsequence sum of .

maxSubarray has the following parameter(s):

arr: an array of integers

Input Format

The first line of input contains a single integer , the number of test cases.

The first line of each test case contains a single integer .
The second line contains space-separated integers where .

Constraints

The subarray and subsequences you consider should have at least one element.

Output Format

Print two space-separated integers denoting the maximum sums of nonempty subarrays and nonempty subsequences, respectively.

Sample Input 0

2
4
1 2 3 4
6
2 -1 2 3 4 -5

Sample Output 0

10 10
10 11

Explanation 0

In the first case: The maximum sum for both types of subsequences is just the sum of all the elements since they are all positive.

In the second case: The subarray is the subarray with the maximum sum, and is the subsequence with the maximum sum.

Sample Input 1

1
5
-2 -3 -1 -4 -6

Sample Output 1

-1 -1

Explanation 1

Since all of the numbers are negative, both the maximum subarray and maximum subsequence sums are made up of one element, .
