Why i am getting error in submitting it showing tle error

#1

#include
using namespace std;
int main()
{
int num,i;
cin>>num;
for(i=0;num!=10;i++)
{
cout<<num%10;
num=num/10;
}
return 0;
}

#2

constraints are large
0 <= N <= 1000000000
so use long long int

also change condition num!=10
use num>0

thank you so much bhaiya:)
