Problem type

Over the course of D days, N players gain or lose T_i points on their base score S_i. At the end of the D days, the top P players make it to the highest division which is called Challenger. Given players, their base scores, and their score change over D days, output the player with the P^{th} highest ranking (the last person to make it to challenger).

Input Specification

The first line of input contains one integer N, the numbers of players (1 \le N \le 10^3).
The next N lines of input will contain a string up to 30 characters long which is the name of each player and their base score S_i (0 \le S_i \le 10^6).
The next line of input will contain a single integer D, the number of days (1 \le D \le 100).
The next D*N lines contain the name of each player and the net change of each player's score T_i (-S_i \le T_i \le 10^6) on the D_{i^{th}} day.
The final line will contain one integer P the number of players that will make it to challenger.
