Flood Fill Algorithm

Explanation

- **Flood Fill** is an algorithm used to determine the area connected to a given node in a multi-dimensional array.
-

• Steps:

  • Start from a given point and mark it as visited.
  • Check neighboring cells and recursively visit all cells that are the same as the starting point.
  • Continue until the entire connected region is filled.

• Time Complexity:

  • O(N), where N is the number of cells in the grid.
