iterate through a 2d array code example

Example 1: how to use loop in 2d array

for (int row = 0; row < board.length; row++) { 
	for (int col = 0; col < board[row].length; col++) { 
    	board[row][col] = row * col; 
        } 
    }

Example 2: iterating over 2d array python

x = [ ['0,0', '0,1'], ['1,0', '1,1'], ['2,0', '2,1'] ]
for i in range(len(x)):
  for j in range(len(x[i])):
    print(x[i][j])
