题目描述

Recently Vasya found a golden ticket — a sequence which consists of $n$ digits $a_1a_2\dots a_n$ . Vasya considers a ticket to be lucky if it can be divided into two or more non-intersecting segments with equal sums. For example, ticket $350178$ is lucky since it can be divided into three segments $350$ , $17$ and $8$ : $3+5+0=1+7=8$ . Note that each digit of sequence should belong to exactly one segment.

Help Vasya! Tell him if the golden ticket he found is lucky or not.

输入格式

The first line contains one integer $n$ ( $2 \le n \le 100$ ) — the number of digits in the ticket.

The second line contains $n$ digits $a_1 a_2 \dots a_n$ ( $0 \le a_i \le 9$ ) — the golden ticket. Digits are printed without spaces.

输出格式

If the golden ticket is lucky then print "YES", otherwise print "NO" (both case insensitive).
