  "Find the greatest product of four numbers in any direction (up, down, left, right, or diagonally) in the 20x20 grid. Append the value at row 16 and column 5 to the result."

  I tried many times but failed.

  Question 1:  if this level is ask me to traverse every postion to find its 4 most big neighbours from all 8 neighbours then calc the prodcut of the four?

  question 2:  if this level is ask me to traverse every postion to calc its up, down, left, right's product then compare the product of its  diagonally four neighbours,choose the bigger one.

  the last question: is the row and column indexed from 0?

  My english is very poor,so I can't understand the question.Can I get some help from here? thanks.

  Row 1 starts from the very first row, column 1 starts from the very first column.

  why I get this? if column 1 starts from the very first column.

  column 0 from what? I am so confused about this level.

    Just checked the code.

    My bad, Yes, row and column both start at 0.

    Have updated the challenge to reflect this.
