Leetcode Solutions

Greedy Approach with Reverse Traversal

  1. Initialize a variable max_sum to 0, which will store the maximum sum encountered.
  2. Start from the second last element of the array and move towards the first element.
  3. For each element, check if it is less than or equal to the sum of elements to its right.
  4. If it is, add the current element to the sum of elements to its right.
  5. Update max_sum with the larger of max_sum and the new sum.
  6. Continue this process until the first element of the array is reached.
  7. Return max_sum as the result.
