totalTrainingHours and currentEnergy, to 0 and initialEnergy, respectively.currentExperience to initialExperience.energy and experience arrays.
a. If currentEnergy is less than or equal to the opponent's energy, train to increase currentEnergy just enough to have one more than the opponent's energy.
b. If currentExperience is less than or equal to the opponent's experience, train to increase currentExperience just enough to have one more than the opponent's experience.
c. Add the number of training hours for energy and experience to totalTrainingHours.
d. Subtract the opponent's energy from currentEnergy and add the opponent's experience to currentExperience.totalTrainingHours as the minimum number of training hours required.
