Given Number of Dice, get all the possible combinations.

Input : K = 2
Output : [(1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (1, 6), (2, 1), (2, 2), (2, 3), (2, 4), (2, 5), (2, 6), (3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (3, 6), (4, 1), (4, 2), (4, 3), (4, 4), (4, 5), (4, 6), (5, 1), (5, 2), (5, 3), (5, 4), (5, 5), (5, 6), (6, 1), (6, 2), (6, 3), (6, 4), (6, 5), (6, 6)]
Explanation : All possible combinations printed.

Input : K = 1
Output : [(1, ), (2, ), (3, ), (4, ), (5, ), (6, )]
Explanation : All possible combinations printed.

Method #1 : Using list comprehension + product()

The combination of above functions can be used to solve this problem. In this, we extract all the possible elements using list comprehension, and in next step, all the possible combination are produced using product().

Method #2 : Using repeat + product()

This is another way in which this task can be performed. In this we use repeat parameter of product to reduce one step to solve this problem, of extraction of elements.
