798. Smallest Rotation with Highest Score

Leetcode Solutions

Interval Stabbing Approach for Best Rotation

  1. Initialize an array bad of the same length as nums with all zeros.
  2. Iterate through each element nums[i].
  3. Calculate the 'bad' interval for each element, which is from i - nums[i] + 1 to i (modulo the array length).
  4. Increment bad[i - nums[i] + 1] and decrement bad[i + 1], handling wrap-around intervals appropriately.
  5. After processing all elements, iterate through bad to calculate the cumulative sum, which represents the number of overlapping 'bad' intervals for each rotation index.
  6. Find the rotation index with the minimum cumulative sum, which corresponds to the maximum score. If there are multiple such indices, return the smallest one.
