Which Team Should Receive the Sponsor Prize?

In ICQC (International Collegiate Quiz Contest), teams compete on how fast they can answer a difficult quiz. The winner is, of course, the team that gives the correct answer first. This year, a sponsor prize also goes to the team whose correct answer time is closest to $2023$ seconds after the contest starts.

Given the elapsed time from the start of the contest until each team gave its correct answer, decide which team receives the sponsor prize.

The input consists of multiple datasets. Each dataset is given in the following format. There are at most $50$ datasets.

$n$ $a_1$ $a_2$ $\cdots$ $a_n$

$n$ is the number of participating teams, where $2 \le n \le 100$. The teams are numbered $1$ through $n$. $a_k$ ($k = 1, \ldots, n$) is the elapsed time in seconds before team $k$ gave its correct answer. It is a positive integer not exceeding $10^4$. You may assume that exactly one team has the elapsed time closest to $2023$ seconds.

The end of the input is a line containing a single $0$.

For each dataset, print the number of the team that receives the sponsor prize on its own line.
