Provide a correct Python 3 solution for this coding contest problem.
It is known that each weight of 1 gram, 3 gram, 9 gram, and 27 gram can be weighed from 1 gram to 40 gram in 1 gram increments using a balance. For example, if you put a weight of 3 grams and a weight you want to weigh on one plate of the balance and... | instruction | 0 | 32,423 | 10 | 64,846 |
