When we are supposed to get a TLE after 10^9 iteration?

When we are supposed to get a TLE after 10^9 iteration?
as bhaiya said that it complexity will reach to 10^9 as complexity is O(q*n) so he make solution of order O(q+n).

Hey @kkunalguptaaa
1 second== 10^9 operations
If its mentioned 2 seconds then 2*10^9 operations and so on
So it will always be mention what is the expected time limit.
