In lines 30 and 34 of the code in this video, bhaiya is using " ll " in the for loop.
for( ll i=3; I<1000000; i+=2)
So what is the ll here? and why is it used in place of int i .
Meaning of " ll "
ll means long long int.
He must have used the statement typedef long long int ll;
This way we don’t have to write long long int again and again. Only ll will do.
