“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 \leq N \leq 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.
