HackerEarth - Maximum Sum Solution

You are given an array of integers A, you need to find the maximum sum that can be obtained by picking some non-empty subset of the array. If there are many such non-empty subsets, choose the one with the maximum number of elements. Print the maximum sum and the number of elements in the chosen subset.

Input:

The first line contains an integer N, denoting the number of elements of the array. The next line contains N space-separated integers, denoting the elements of the array.

Output:

Print 2 space-separated integers, the maximum sum that can be obtained by choosing some subset and the maximum number of elements among all such subsets which have the same maximum sum.

Constraints:

1≤N≤105

−109≤Ai≤109

SAMPLE INPUT

5
1 2 -4 -2 3

SAMPLE OUTPUT

6 3

Explanation

The chosen subset is {1, 2, 3}.

Solution in Python#

n = int(input())
a = list(map(int,input().split()))
m = [i for i in a if i>=0] or [max(i for i in a if i<0)]
print(sum(m),len(m))

Explanation

The sum of all the values greater than or equal to 0 is our required value.

However all numbers might be negative in some cases. In that case we will choose the greatest number among all the negative values.
