MAXSUB - Maximum Subset of Array |
Given an array find the sum of the maximum non-empty subset of the array and also give the count of the subset. A subset of an array is a list obtained by striking off some (possibly none) numbers.
A non-empty subset implies a subset with at least 1 element in it.
Input
First line contains an integer T which is the number of integers. Following this T-cases exist.
Each case starts with a line containing an integer n which is the number of elements in the array.
The next line contains n-integers which contain the value of this subset.
Constraints
T <= 20
n <= 50,000
Each element in the array <= 1,000,000,000
Output
For each test case output the value of the maximum subset and the count of the subsets modulo 1000,000,009
Example
Input: 2 5 1 -1 1 -1 1 6 -200 -100 -100 -400 -232 -450 Output: 3 1 -100 2

"count of the subset" means the number of different subsets that have minimal sum, not the number of subsets elements. |

This is a very trivial problem. Should I move to tutorial, or anybody has an idea for challenge? (Lowest source code) |
