Paper Dice
This mission is the advanced version of the 'Identify Block' mission.
You have to write a code to check the development of drawing a die.
The input represents the development of drawing one die. It's a list of strings. These strings are of the same length. They consist of 1 to 6 digits and a space. These digits represent each side of the die.
- If the development is correct, return True.
- If the followng cases, return False:
- You can't complete a cube.
- The sum of the top and bottom sides doesn't always equals 7.
11 nets of a cube.
Example:
paper_dice([' 1 ',
' 235 ',
' 6 ',
' 4 ']) == True
paper_dice([' ',
'12 ',
' 36 ',
' 54',
' ']) == True
paper_dice(['123456']) == False
paper_dice(['123 ',
' 456']) == False
Input: A list of strings.
Output: The answer as a boolean.
Precondition:
- all(len(row) == len(paper[0]) for row in paper)
- all((cell in '123456 ' for cell in row) for row in paper)
