如何生成数组的组合，并将每个组合中的数字除以同一组合中的数字的乘积？

def generate_combinations(nums):
    if len(nums) == 0:
        return [[]]

    result = []
    for i in range(len(nums)):
        current_num = nums[i]
        remaining_nums = nums[:i] + nums[i+1:]
        combinations = generate_combinations(remaining_nums)
        for combination in combinations:
            result.append([current_num] + combination)

    return result

def calculate_division(combinations):
    result = []
    for combination in combinations:
        product = 1
        for num in combination:
            product *= num
        division = [num / product for num in combination]
        result.append(division)

    return result

nums = [1, 2, 3]
combinations = generate_combinations(nums)
result = calculate_division(combinations)
print(result)
