Hedonian professor

In the land of Hedonia the offcial language is Hedonian. A Hedonian professor had noticed that many of her students still did not master the syntax of Hedonian well. Tired of correcting the many syntactical mistakes, she decided to challenge the students and asked them to write a program that could check the syntactical correctness of any sentence they wrote. Similar to the nature of Hedonians, the syntax of Hedonian is also pleasantly simple. Here are the rules:
0. The only characters in the language are the characters p through z and N, C, D, E, and I.
1. Every character from p through z is a correct sentence.
2. If s is a correct sentence, then so is Ns.
3. If s and t are correct sentences, then so are Cst, Dst, Est and Ist.
4. Rules 0. to 3. are the only rules to determine the syntactical correctness of a sentence.
You are asked to write a program that checks if sentences satisfy the syntax rules given in Rule 0. - Rule 4.

Input

The input consists of a number of sentences consisting only of characters p through z and N, C, D, E, and I. Each sentence is ended by a new-line character. The collection of sentences is terminated by the end-of- file character. If necessary, you may assume that each sentence has at most 256 characters and at least 1 character.

Output

The output consists of the answers YES for each well-formed sentence and NO for each not-well-formed sentence. The answers are given in the same order as the sentences. Each answer is followed by a new-line character, and the list of answers is followed by an end-of- file character.

Example

Input: Cp Isz NIsz Cqpq Output: NO YES YES NOq2

Alice is very fond of prime numbers. Given a number she wants to determine whether it is prime or not. If a number is prime she wants to know that which prime number is it.
e.g. 2 is 1st prime number,3 is 2nd and so on.

Input

First line of input contains number of test cases t. t lines follow. Each line contains a positive integer(

Output

For each test case output a single integer. If the number is not prime output -1 otherwise output a integer say n such that the number is nth prime number.

Example

Input: 3 2 3 4 Output: 1 2 -1
