    - DP where bitmask tracks both where we are and which locations have been
      visited; table size is 21 * (1 << 21); runtime O(L^2 * 2^L + L * 2^M)
      for L locations and M pokemons.

    - not sure; DP on 20 * (1 << 15), so probably similar to bowen-dp-pokemon.cpp

AC submission PokeMonGodmar.java (Java) OK: AC [CPU: 1.21s @ test case secret/17]
    - DP similar to bowen-dp-location.cpp

AC submission Pokemon.java (Java) OK: AC [CPU: 2.74s @ test case secret/1]
    - backtracking with pruning; only non-DP solution
