Thank you very much for this solution, I was following a simillar, but more complex approach, which wasn't working.

Strange that it doesn't need to set n = len(x).

Excellent solution man, Can you tell if there are houses all over from 1 to n but the given array represents that we can install the tower only on that houses. This means we have to cover the full range from 1 to max house by minimum tower
