Problem Description

Password security is a tricky thing. Users prefer simple passwords that are easy to remember (like buddy), but such passwords are often insecure. Some sites use random computer-generated passwords (like xvtpzyo), but users have a hard time remembering them and sometimes leave them written on notes stuck to their computer. One potential solution is to generate "pronounceable" passwords that are relatively secure but still easy to remember.

FnordCom is developing such a password generator. You work in the quality control department, and it's your job to test the generator and make sure that the passwords are acceptable. To be acceptable, a password must satisfy these three rules:

It must contain at least one vowel.

It cannot contain three consecutive vowels or three consecutive consonants.

It cannot contain two consecutive occurrences of the same letter, except for 'ee' or 'oo'.

(For the purposes of this problem, the vowels are 'a', 'e', 'i', 'o', and 'u'; all other letters are consonants.) Note that these rules are not perfect; there are many common/pronounceable words that are not acceptable.

 

Input

The input consists of one or more potential passwords, one per line, followed by a line containing only the word 'end' that signals the end of the file. Each password is at least one and at most twenty letters long and consists only of lowercase letters.

 

Output

For each password, output whether or not it is acceptable, using the precise format shown in the example.

 

Sample Input

a
tv
ptoui
bontres
zoggax
wiinq
eep
houctuh
end

 

Sample Output

<a> is acceptable.
<tv> is not acceptable.
<ptoui> is not acceptable.
<bontres> is not acceptable.
<zoggax> is not acceptable.
<wiinq> is not acceptable.
<eep> is acceptable.
<houctuh> is acceptable.

 题目大意

       判断给定的密码串是否符合要求。

       1、它必须包含至少一个元音。

       2、它不能包含三个元音字母或三个连续的辅音。

       3、它不能包含两个连续的相同的字母，除了“EE”或“OO”。

解题思路

       根据题目要求一次判断就好，可以通过动态规划定义一个子连来判断连续了几次。

char a[25];
int d[25];
int judge(char c)
{
	if(c=='a'||c=='e'||c=='i'||c=='o'||c=='u')
	    return 1;
	else
	    return 0;
}//区分原音和辅音 
void mima(char b[])

	int len;
	int i,j,k;
	int ok,nowl;
	int num;

			if(b[i]==b[i-1]&&!(b[i]=='e'||b[i]=='o'))//判断是否连续两个相同 
			{
				ok=0;

			}
		}
		else
		    nowl=1;//子连初始化 
	}
	num=0;
	for(i=0;i<len;i++)
	    if(d[i]==1)
	        num++;//判断条件1 
	if(ok==1&&num>0)
	    printf("<%s> is acceptable.\n",b);
	else if(ok==1&&num==0)
	    printf("<%s> is not acceptable.\n",b);
