Problem Statement
翻译中…
Print a sequence $a_1, a_2, ..., a_N$ whose length is $N$ that satisfies the following conditions:
翻译中…
$a_i$$(1 \leq i \leq N)$is a prime number at most$55$$555$.- The values of
$a_1, a_2, ..., a_N$are all different. - In every choice of five different integers from
$a_1, a_2, ..., a_N$, the sum of those integers is a composite number.
翻译中…
If there are multiple such sequences, printing any of them is accepted.
翻译中…
Note
翻译中…
An integer $N$ not less than $2$ is called a prime number if it cannot be divided evenly by any integers except $1$ and $N$, and called a composite number otherwise.
翻译中…
Constraints
翻译中…
$N$is an integer between$5$and$55$(inclusive).

样例
Input #1
5
Output #1
3 5 7 11 31
Let us see if this output actually satisfies the conditions.
First, $3$, $5$, $7$, $11$ and $31$ are all different, and all of them are prime numbers.
The only way to choose five among them is to choose all of them, whose sum is $a_1+a_2+a_3+a_4+a_5=57$, which is a composite number.
There are also other possible outputs, such as `2 3 5 7 13`, `11 13 17 19 31` and `7 11 5 31 3`.
Input #2
6
Output #2
2 3 5 7 11 13
- $2$, $3$, $5$, $7$, $11$, $13$ are all different prime numbers.
- $2+3+5+7+11=28$ is a composite number.
- $2+3+5+7+13=30$ is a composite number.
- $2+3+5+11+13=34$ is a composite number.
- $2+3+7+11+13=36$ is a composite number.
- $2+5+7+11+13=38$ is a composite number.
- $3+5+7+11+13=39$ is a composite number.
Thus, the sequence `2 3 5 7 11 13` satisfies the conditions.
Input #3
8
Output #3
2 5 7 13 19 37 67 79
