CodeChefOpen on judge ↗

SubarraySet of an array is defined as the set of sum of each subarray of the array. More formally for array A, SubarraySet of A consists of Ai + Ai+1 .. Aj for 1 ≤ i ≤ j ≤ N .For example, SubarraySet of array [1,2,5] is the set {1,2,3,5,7,8}. A is an array of positive integers having N elements. The elements of the array are not known. However, it is known that the sum of all elements of A is S.
