生育政策与男女比例 (Fertility Policy)
Problem
Question
If a family stops having children after giving birth to a boy, and continues to have children after giving birth to a girl until a boy is born, the question is: What will the gender ratio be in this place?
如果一个家庭生下男孩就不再生孩子，如果是女孩子就继续生，直到生出男孩为止，问：这个地方的男女比例会是多少？
