Question

我正在尝试根据用户输入的总人数计算房间总数。最多人数不能超过7人。房间类型为双床间（每间客房2人 - 成人和儿童），双人间（每间客房2人 - 成人和儿童），单人间（每间客房1人）和加床。人的类型是成人，带床的孩子和没有床的孩子。

对于房间计算，我们需要添加[（成人+带床的孩子/ 2）]以获得房间价值。默认情况下，系统必须将房间数放在双人共享中。带床的儿童必须与成人一起入住双床间。所以，任何超过奇数的都将导致单人间。

示例：4名成人和1名儿童;共5人。结果：2间双床房和1间单人房。

用户可以通过将双人床改为双人床或加床来改变这一结果。结果：2张双人床和1张加床。加床与双人间相连。

我需要一些帮助才能在JavaScript中使用此功能。到目前为止，我设法进行了系统计算，但是当尝试通过手动进行更改时，它会导致计算错误。

示例：4名成人和1名儿童;共5人。默认值：2间双床房和1间单人房。用户更改为1个双胞胎（必须至少有1个双胞胎，因为有一个孩子），单人可以最多2个房间，余额1个成人可以选择1个加床。
