Codeforces is a website that hosts competitive programming contests. It is maintained by a group of competitive programmers from ITMO University. Since 2013, Codeforces claims to surpass Topcoder in terms of active contestants. As of 2018, it has over 600,000 registered users. Codeforces along with other similar websites are used by top sport programmers and by other programmers interested in furthering their career. Codeforces is recommended by many universities. According to Daniel Sleator, professor of Computer Science at Carnegie Mellon University, competitive programming is valuable in computer science education, because competitors learn to adapt classic algorithms to new problems, thereby improving their understanding of algorithmic concepts.
In codeforces contestants are divided into ranks based on their ratings：

≥3000	Legendary Grandmaster
2400 - 2999	Grandmaster
2100 - 2399	Master

After a contest, the rating of the contestant will change. In this problem, you are given a contestant's rating before and after the contest. You need to answer whether the title has changed. If it has changed, please output the original and changed title.

The first line contains an integer  — the number of test cases, each test case contains two integers  and  representing contestant's rating before and after the contest.
