      Sigrún got a lot of presents from all the guests that attended her birthday party today. She has opened all the gifts and noticed that they weren’t equally fun.
She made a list of all the gifts she got, from whom she got each gift and a number denoting how much she enjoyed the gift — the higher the number, the more fun the gift is.
Can you help Sigrún find who gave her the most fun gift?
Input
The first line contains a single integer $n$ ($1 \leq n \leq 1\, 000$), the number of guests who attended the party and gave Sigrún a gift. Then there are $n$ lines, each containing the name of a guest and an integer denoting how fun the gift from this guest was. Each name only contains English letters, no spaces and is at most $20$ characters long. Furthermore, each integer is in the interval $0$ to $1\, 000$. No two values are the same.
Output
Print a single line containing the name of the guest that gave Sigrún the most fun gift.
