Use numbers and basic arithmetic operations (+ - * /) to obtain 24. Each step, you are only allowed to choose two of the remaining numbers to obtain a new number. Input: 4 4 6 8 Steps: 4 + 8 = 12 (left: 4 6 12) 6 - 4 = 2 (left: 2 12) 2 * 12 = 24 (left: 24) Answer: (6 - 4) * (4 + 8) = 24 Input: 2 9 10 12 Steps: 12 * 2 = 24 (left: 9 10 24) 10 - 9 = 1 (left: 1 24) 24 * 1 = 24 (left: 24) Answer: (12 * 2) * (10 - 9) = 24 Input: 4 9 10 13 Steps: 13 - 10 = 3 (left: 3 4 9) 9 - 3 = 6 (left: 4 6) 4 * 6 = 24 (left: 24) Answer: 4 * (9 - (13 - 10)) = 24 Input: 1 4 8 8 Steps: 8 / 4 = 2 (left: 1 2 8) 1 + 2 = 3 (left: 3 8) 3 * 8 = 24 (left: 24) Answer: (1 + 8 / 4) * 8 = 24 Input: 5 5 5 9 Steps: 5 + 5 = 10 (left: 5 9 10) 10 + 5 = 15 (left: 9 15) 15 + 9 = 24 (left: 24) Answer: ((5 + 5) + 5) + 9 = 24 Input: {Puzzles} Steps:
