DFS Approach to Validate Knight's Tour

  1. Check if the starting cell is 0, if not return false.
  2. Define the 8 possible moves a knight can make.
  3. Use a recursive DFS function to traverse the grid.
    • The function should take the current position and the number of steps taken.
    • If the current cell value is equal to n*n - 1, return true as we have completed the tour.
    • For each of the 8 moves, calculate the new position.
    • If the new position is within bounds and the cell value is equal to the current number of steps + 1, recursively call the DFS function for the new position.
    • If none of the moves lead to a solution, return false.
  4. Call the DFS function starting from the top-left cell with 0 steps taken.
  5. Return the result of the DFS function.
