The Next Wave Energy Research Club is looking at several atoms as potential energy sources, and has asked you to do some computations to see which are the most promising.
Although an atom is composed of various parts, for the purposes of this method only the number of neutrons in the atom is relevant (In fact, for this problem you might want to forget everything you thought you knew about chemistry.). In the method, a laser charge is fired at the atom, which then releases energy in a process formally called explodification. Exactly how this process proceeds depends on the number of neutrons $k$:
When an atom with $k$ neutrons is explodificated, the total energy that is released depends on the exact sequence of decompositions that occurs in the explodification process. Modern physics is not powerful enough to predict exactly how an atom will decompose---however, for explodification to be a reliable energy source, we need to know the minimum amount of energy that it can release upon explodification. You have been tasked with computing this quantity.
The input consists of:
For each query $k$, output the minimum energy released when an atom with $k$ neutrons is explodificated.
