Hina Arare

题目描述

In Japan, people make offerings called hina arare, colorful crackers, on March 33.

We have a bag that contains NN hina arare. (From here, we call them arare.)

It is known that the bag either contains arare in three colors: pink, white and green, or contains arare in four colors: pink, white, green and yellow.

We have taken out the arare in the bag one by one, and the color of the ii-th arare was SiS_i, where colors are represented as follows - pink: P, white: W, green: G, yellow: Y.

If the number of colors of the arare in the bag was three, print Three; if the number of colors was four, print Four.

在日本,人们会在三月 33 这一天制作名为 hina arare 的祭品,即五颜六色的饼干。

我们有一个袋子,里面装着 NNhina arare (后面我们都称之为阿拉蕾)。

众所周知,袋子里的阿拉蕾要么有三种颜色:粉色、白色和绿色,要么有四种颜色:粉色、白色、绿色和黄色。

我们将袋子里的阿拉蕾逐一取出, 第 ii 个阿拉蕾的颜色是 SiS_i ,其中颜色的表示方法如下--粉色:P,白色:W,绿色:G,黄色:Y.

如果袋子里的阿拉蕾的颜色数是三种,则打印 Three;如果颜色数是四种,则打印 Four
