1872. Stone Game VIII

Leetcode Solutions

Dynamic Programming with Prefix Sums

  1. Calculate the prefix sum array of the stones.
  2. Initialize a variable dp to the last value of the prefix sum array, which represents the score difference if the game starts with only the last stone.
  3. Iterate backwards through the stones array starting from the second to last element.
  4. At each step, update dp to be the maximum of the current dp and the difference between the current prefix sum and dp.
  5. The final value of dp after the loop is the answer to the problem.
