Pagodas

题目描述

nn pagodas were standing erect in Hong Jue Si between the Niushou Mountain and the Yuntai Mountain, labelled from 1 to nn. However, only two of them (labelled aa and bb, where 11aabbnn) withstood the test of time.

Two monks, Yuwgna and Iaka, decide to make glories great again. They take turns to build pagodas and Yuwgna takes first. For each turn, one can rebuild a new pagodas labelled ii (i(i∉{aa,bb} and 11iinn )) if there exist two pagodas standing erect, labelled jj and kk respectively, such that i=j+ki=j+k or i=ji=jkk. Each pagoda can not be rebuilt twice.

This is a game for them. The monk who can not rebuild a new pagoda will lose the game.

输入格式

The first line contains an integer tt (11tt500500) which is the number of test cases. For each test case, the first line provides the positive integer n(2n (2nn20000)20000) and two different integers aa and bb.

输出格式

For each test case, output the winner ("Yuwgna" or "Iaka"). Both of them will make the best possible decision each time.
