Leetcode Solutions

Prefix Sum of Factors and

  1. Iterate over the grid and calculate the number of factors of 2 and 5 for each cell.
  2. Create four prefix sum matrices to store the cumulative count of factors of 2 and 5 in all four directions (up, down, left, right).
  3. For each cell in the grid, calculate the product of factors for the four possible cornered paths.
  4. For each path, determine the minimum count of factors of 2 and 5, as this will be the number of trailing zeros for that path.
  5. Keep track of the maximum number of trailing zeros found across all paths.
  6. Return the maximum number of trailing zeros found.
