2D List Mystery Consider the following method: def mystery (data, pos, n): result set () for i in range (0, n): for j in range (0, n): return result Suppose that a variable called grid has been declared as follows: grid = [[8, 2, 7, 8, 2, 1], [1, 5, 1, 7, 4, 71, [5, 9, 6, 7, 3, 2], [7, 8, 7, 7, 7, 91, [4, 2, 6, 9, 2, 3], [2, 2, 8, 1, 1, 3]] 8 1 5 7 4 2 which means it will store the following 6-by-6 grid of values: 2 7 2 4 3 7 In 980NN 5 result.add(data[i+ pos] [j + pos]) 2 2 16760 00 8 7 mystery (grid, 2, 2) mystery (grid, 0, 2) mystery (grid, 3, 3) 7 7 9 8 1 For each call below, indicate what value is returned. If the function call results in an error, write "error" instead. Function Call Contents of Set Returned 2 1 7 2 1 9 3 3
