"In mathematics, theorems are named after the second person to discover them, for the first is always Euler."
Leonhard Euler was a brilliant mathematician who made significant advancements in many areas of math and science, and hence has a lot of things named after him. In this problem, you will figure out whether Euler was the first one to discover a theorem.
A test case begins with an integer ~N~ ~(1 \le N \le 1000)~. ~N~ lines follow, each containing a person's name ~S~ and a year ~Y~, which means that person ~S~ discovered the theorem in year ~Y~. No two people will discover a theorem in the same year.
Output the name of the first person to discover the theorem.
