Can You Build a Pyramid from Dominoes?
Is it possible to build a pyramid from these dominoes, as described in the problem?
Write a function that, given an array consisting of twelve integers, returns the string "YES" if it is possible to build a correct pyramid from these dominoes or "NO" otherwise.
Answer:
The problem is related to arranging domino pieces in a pyramid shape. We need at least three pairs of identical dominos to build the pyramid. The function should return 'YES' if these conditions are met, otherwise it returns 'NO'.
The problem described in the question relates to sorting and matching values, which is a common problem in the field of computer science and programming. In the context of this problem, we are thinking about arranging domino pieces in a pyramid shape following specific rules regarding the number of spots on each domino half.
Considering the condition provided, we can solve this problem by realizing that each domino at level n-1 is directly under two dominos at level n. Given that the spots should be equal, any domino in level n-1 should have two identical halves. Since we cannot have more than six identical halves (one domino consists of two halves, and we only have six dominos), the maximum level of the pyramid could be three.
If we assume that the dominos can be flipped, we would need at least three pairs of identical dominos (each with the same dots on both sides) to construct the pyramid as per the requirements. If these conditions are met, we can return "YES"; otherwise, the function should return "NO".
