Hello @yashsingh9289,

Please, share your code.
That will help me to identify your mistake.

Possible mistake:
You might be passing sum as 0, initially.
So, it will be true for sure for the case when you would add no element to sum.
Example:
2
1 2 3 4

Hope, this would help.

#include
using namespace std;
void sub(char arr[],char out[],bool &ischeck,int opos,int spos)
{
if(arr[spos]==’\0’)
{int sum=0;
out[opos]=’\0’;
for(int i=0;out[i]!=’\0’;i++)
{
sum=sum+(out[i]-‘0’);
}if(sum==0&&out[0]!=’\0’)
{

    ischeck=true;
}

return;
}

out[opos]=arr[spos];

sub(arr,out,ischeck,opos+1,spos+1);
sub(arr,out,ischeck,opos,spos+1);

}
int main()
{int t;cin>>t;
int n;cin>>n;
char arr[100],out[100];
bool ischeck=false;
for(int j=1;j<=t;j++)
{for(int i=0;i<n;i++)
{cin>>arr[i];}
sub(arr,out,ischeck,0,0);
if(ischeck) {cout<<“YES”<<endl;ischeck=false;}
else {cout<<“NO”<<endl;ischeck=true;}
}

}
