Count Distinct Subsets Sum
You are given an array of non-negative integers. Your task is to count the number of distinct sums that can be formed by subsets of this array. Two subsets that create the same sum count as one, and the empty subset (sum 0) is also counted. For example, given the array [1, 2, 2], the distinct sums are {0, 1, 2, 3, 4}.
Input Format:
- The first line contains an integer n (1 ≤ n ≤ 100), the number of elements in the array.
- The second line contains n space-separated integers, the elements of the array.
Output Format:
- Output a single integer, the count of distinct subsets sums.
Example:
Input:
3
1 2 2
Output:
5
