hi @Riya-Verma-1207263756078812,
if num is 0 you should print 5 but as your condition is while(num != 0) so it wont enter the while loop
just handle this case

you can write in main

long long int num;
	cin >> num;
	if(num == 0){ // to handle this case
		cout<<5;
		return 0;
	}
	cout << replaceThemall(num);
       return 0;
}```
