One solution is to use an Adjacency List to keep track of the edges (bonds) between the vertices (atoms). You can then determine whether each atom is a Carbon or Hydrogen based on the number of bonds and count their respective frequencies. Afterwards, for each atom, add the required bond energy to the total value and remember to take double-bonds into account.
