Hello @pragyachoudhary1111,

You are taking wrong inputs.
t : no. of test cases.
n: no. of elements in the array.
m: What is this?

Please, read the question properly.

Hope, this would help.
Give a like, if you are satisfied.

Hey @pragyachoudhary1111,

The base case that you are using are contradictory:
if (n == 0)
return true;
if (n == 0 && sum != 0)
return false;

To satisfy second if-condition, n should be 0.
If n is 0 then first if-condition would satisfy and second if-condition would never execute.

You can refer to the following approach also:
bool isSubsetSum(int *arr,int i,int n){
if(i==n)
return false;
int sum=0;
for(int j=i;j<n;j++){
sum+=arr[j];
if(sum==0)
return true;
}
return zero(arr,i+1,n);
}

Let me know if you still have any issue.
