Shooting submarine on a number line! (Posted on 2019-06-08) Difficulty: 3 of 5
There is an enemy submarine located at an unknown integer somewhere on the number line. The submarine is moving at a constant integer distance per minute (also unknown, and can be positive or negative). Every minute, you can fire a missile at an integer on the number line in an attempt to destroy the submarine.

Is there a strategy to strike the submarine in a finite amount of time?

Assume that you move first and that you can fire missiles at the number line for as long you need to.

Waiting for official releases is sometimes safer than downloading APKs. Some users prefer to freecine site install applications directly from the app store to avoid security risks. However, those needing early access or unavailable apps may consider APKs from reputable sources.
