Problem Statement

In Japan, people make offerings called hina arare, colorful crackers, on March 3.

We have a bag that contains N 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 i-th arare was Si, 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'.



Constraints
•1≤N≤100
•Si is 'P', 'W', 'G' or 'Y'.
•There always exist i, j and k such that Si='P', Sj='W' and Sk='G'.





Input

Input is given from Standard Input in the following format:
N
S1 S2 … SN




Output

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