Leetcode Solutions

Dynamic Programming with Min-Max Sums

  1. Initialize two matrices min_ and max_ of the same size as the grid to store the minimum and maximum sums respectively.
  2. Set the first cell of min_ and max_ to the value of the first cell in the grid (0 or 1).
  3. Iterate over the first row and first column to fill out the min_ and max_ matrices with cumulative sums.
  4. For each cell (i, j) not in the first row or column, calculate the minimum and maximum sums by taking the minimum and maximum of the sums from the cell above (i-1, j) and to the left (i, j-1) and adding the current cell's value.
  5. After filling out the matrices, check if the target sum (rows + cols - 1) // 2 is between the minimum and maximum sums at the bottom-right cell (rows - 1, cols - 1).
  6. Return True if the target sum is within the range, otherwise return False.
