A sequence $S$ of positive integers is a composite sequence if and only if there is a non-empty subsequence $T$ of $S$ such that the sum of all integers in $T$ is a composite number.
Given $S$, your task is to check whether $S$ is a composite sequence.
Note that $1$ is not a composite number.
Recall that $T$ is a subsequence of $S$ if and only if we can obtain $T$ by removing some elements of $S$ (possibly none or all).
The first line contains a single integer $n$ ($1 \le n \le 10^5$), the size of $S$.
The second line contains $n$ integers $S_1, S_2, \ldots, S_n$: the elements of $S$ ($1 \le S_i \le 10^9$).
If $S$ is a composite sequence, output "Yes
". Otherwise, output "No
".
