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.


-----Input-----

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.


-----Output-----

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


-----Examples-----
Input
5
73452

Output
YES

Input
4
1248

Output
NO



-----Note-----

In the first example the ticket can be divided into $7$, $34$ and $52$: $7=3+4=5+2$.

In the second example it is impossible to divide ticket into segments with equal sum.
