approach this problem as subset sum problem…in which you are given a target sum as 0…every element has two options either it can be a part of the subset or it cant be a part of the subset…in the base case you can check whether the sum is equal to 0…if it is equal to 0 then you can update a global boolean variable…in main after the execution of your subset function you can check the value of that boolean variable and print the ans accordingly…
