Hexagonal Grid

    My python3 example with O(n) complexity:

    def hexagonalGrid(a, b):
    if ((a.count('1') + b.count('1')) % 2 != 0):
        return 'NO'
    white = 0
    block = False
    for i in range(len(a)):
        if (a[i] == '1'):
            if block and white % 2 != 0:
                return 'NO'
            block = True
        elif (a[i] == '0'):
            block = False
            white += 1
        if (b[i] == '1'):
            if block and white % 2 != 0:
                return 'NO'
            block = True
        elif (b[i] == '0'):
            block = False
            white += 1          
    return 'YES'
