Vietnam Travel Query

Hello everyone, I am planning to travel Vietnam. With a valid single entry visa, can my entry and exit points be from the same airport (In my case its Hanoi). From Hanoi Im planning to travel to Da Nang through air route domestically and from Da Nang I will return back to Hanoi (Air) and take flight back to india.

with a single entry visa, will this plan be possible !! With flight rates and everything only this plan is costing me less compared to exiting directly from Da Nang ?

Here is my plan: Hyd to Hanoi —> Hanoi to DaNang —> Da Nang to Hanoi —> Hanoi to Hyderabad

With single entry visa and taking entry and exit points will this plan possible ?
