5577: Shampoo洗发水（ABC243A)

Problem Statement:

Three people live in Xiaoniu's house: Xiaoniu, his father, and his mother. All of them wash their hair in the bathroom each night.  
His father, his mother, and  Xiaoniu take a bath in this order and use $A$, $B$, and $C$ milliliters of shampoo, respectively.

This morning, the bottle contained $V$ milliliters of shampoo. Without refilling, who will be the first to run short of shampoo to wash their hair?

小牛家里住着三个人：小牛、他的父亲和他的母亲。他们每天晚上都在浴室洗头。他的父亲、母亲和小牛按这个顺序洗澡，分别使用 A、B 和 C 毫升的洗发水。今天早上，瓶子里含有 V 毫升的洗发水。在不补充的情况下，谁会第一个用完洗头的洗发水？

If the first person to run short of shampoo to wash their hair is Takahashi's father, print `F`; if it is Takahashi's mother, print `M`; if it is Takahashi, print `T`.

如果第一个用完洗发水的人是小高的父亲，输出 F；如果是小高的母亲，输出 M；如果是小高，输出 T。
