"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.

Input

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

Output the name of the first person to discover the theorem.
