3259. Maximum Energy Boost From Two Drinks

Medium
ArrayDynamic Programming

Problem Explanation

Explanation:

To maximize the total energy boost, we need to consider the best strategy for each hour. We can switch between energy drinks every hour, but we have to wait for one hour to switch drinks. We can track the maximum energy boost we can get at each hour by considering the options of continuing with the same drink or switching to the other drink.

  1. Initialize two variables drinkA and drinkB to store the maximum energy boost we can get if we drink A or B at the current hour.
  2. Iterate through each hour and update drinkA and drinkB based on the maximum energy boost we can get considering the current hour.
  3. At each hour, we consider two options:
    • If we drink A at the current hour, the maximum energy boost is drinkA + energyDrinkA[i] or drinkB + energyDrinkA[i] if we switch from B to A.
    • If we drink B at the current hour, the maximum energy boost is drinkB + energyDrinkB[i] or drinkA + energyDrinkB[i] if we switch from A to B.
  4. The final result is the maximum value between drinkA and drinkB.

Time Complexity: O(n) where n is the length of the input arrays. Space Complexity: O(1)

Solution Code

class Solution {
    public int maxEnergy(int[] energyDrinkA, int[] energyDrinkB) {
        int drinkA = 0, drinkB = 0;
        for (int i = 0; i < energyDrinkA.length; i++) {
            int nextDrinkA = Math.max(drinkA, drinkB + energyDrinkA[i]);
            int nextDrinkB = Math.max(drinkB, drinkA + energyDrinkB[i]);
            drinkA = nextDrinkA;
            drinkB = nextDrinkB;
        }
        return Math.max(drinkA, drinkB);
    }
}
