Let A = (A1, A2, A3,.....Ai) be defined as a sequence containing positive and negative integer numbers. A substring is defined as (An, An+1,.....Am) where 1 <= n < m <= i. Now, the weight of the substring is the sum of all its elements. Showing your algorithms and proper working: 1) Does there exist a substring with no weight or zero weight? 2) Please list the substring which contains the maximum weight found in the sequence.
