The winner of the card game popular in Berland "Berlogging" is determined according to the following rules. If at the end of the game there is only one player with the maximum number of points, he is the winner. The situation becomes more difficult if the number of such players is more than one. During each round a player gains or loses a particular number of points. In the course of the game the number of points is registered in the line "name score", wherename is a player's name, and score is the number of points gained in this round, which is an integer number. If score is negative, this means that the player has lost in the round. So, if two or more players have the maximum number of points (say, it equals tom) at the end of the game, than wins the oneof them who scored at leastm points first. Initially each player has 0 points. It's guaranteed that at the end of the game at least one player has a positive number of points.

Input

The first line contains an integer number n (1  ≤  n  ≤  1000),n is the number of rounds played. Then follown lines, containing the information about the rounds in "name score" format in chronological order, wherename is a string of lower-case Latin letters with the length from 1 to 32, andscore is an integer number between -1000 and 1000, inclusive.

Output

Print the name of the winner.
