Hello @umnah1103_2205d5eee7973385,

In your Dsum function, you are not doing n = n%10,

while(n!=0){
sum=sum+n%10;
n = n%10;
}

#3

same issue after adding n=n/10;

#4

@umnah1103_2205d5eee7973385,

Here, this is wrong way,

for(int i=2;i*i<=n;i=i++)

Correct way:

for(int i=2;i*i<=n;i=++i)

#5

@umnah1103_2205d5eee7973385,

Did it work?

not working, please check this one - include using namespace std; int sod(int n){ int sum=0; while(n!=0){ sum=sum+n%10; n=n/10; } return sum; } int boston(int n){ int s=0; int t=n; while(n%2==0){ s=s+2; n=n/2; } for(int i=3;i<=t/2;i=i+2){ while(n%i==0){ s=s+sod(i); } } if(n>2||s!=sod(t)) return 0; else return 1; } int main() { int n; cin>>n; cout<<boston(n); return 0; }
