In mathematics, a **semiprime number** is a natural number that is the product of exactly two prime numbers. For example: 4, 6, 9, 10, 14, 15, 21, 22 are the first eight semiprime numbers. Given a set of numbers, one should be able to identify semiprime numbers contained in that set.

The input file **DATA1.txt** will contain five integers, one per line. 1 ≤ `N` ≤ 1000.

The output file **OUT1.txt** will contain five lines, stating if the supplied integers were *“semiprime”* or *“not”*. Use the exact string output, all lower case, without quotes.

Sample Input:

```
2
3
4
5
6
```

Sample Output:

```
not
not
semiprime
not
