29. chessBoardCellColor

Task

Given two cells on the standard chess board, determine whether they have the same color or not.

Example

• For cell1 = "A1" and cell2 = "C3", the output should be
  chessBoardCellColor(cell1, cell2) = true.
• For cell1 = "A1" and cell2 = "H3", the output should be
  chessBoardCellColor(cell1, cell2) = false.

Input/Output

• [execution time limit]
  4 seconds (py3)

• [input] string cell1
  Guaranteed constraints: cell1.length = 2, 'A' ≤ cell1[0] ≤ 'H', 1 ≤ cell1[1] ≤ 8.

• [input] string cell2
  Guaranteed constraints: cell2.length = 2, 'A' ≤ cell2[0] ≤ 'H', 1 ≤ cell2[1] ≤ 8.

• [output] boolean
  true if both cells have the same color, false otherwise.

My Solution

def chessBoardCellColor(cell1, cell2):
    return (ord(cell1[0]) + int(cell1[1]) + ord(cell2[0]) + int(cell2[1])) % 2 == 0
