2297. Jump Game VIII

Leetcode Solutions

Dynamic Programming with Monotonic Stack

  1. Initialize two arrays, nextGreaterOrEqual and nextSmaller, to store the indices of the next greater or equal and next smaller elements for each index in nums.\n2. Use a monotonic stack to populate nextGreaterOrEqual and nextSmaller.\n3. Initialize a DP array minCost with infinite values, except for the first element which should be 0 (since there is no cost to start at index 0).\n4. Iterate through each index in nums, and for each index, update the minCost for its next greater or equal and next smaller indices based on the current minCost and the costs to jump to those indices.\n5. Return the value of minCost at the last index, which represents the minimum cost to reach the end of the array.
