Problem

After years of scanning the skies, humans have finally found evidence of extraterrestrial life. From a dark patch of the sky came an alien transmission - an attempt at contact. After months of painstaking analysis, it was determined that the aliens spoke two languages: Vibberish and Cibberish.

Vibberish is a smooth and simple language that mostly uses words that have more vowels than consonants. On the other hand, the difficult-to-pronounce Cibberish language prefers words with more consonants than vowels.

As the leading computer scientist at SETI, you have been tasked with detecting the language of a transmission. Given a sentence from the transmission, determine whether it is more likely to be Vibberish or Cibberish. (For our purposes, only a, e, i, o, and u are considered vowels).

Input

Each test case contains one sentence of the alien transmission. The sentence will contain only lowercase letters and spaces.

Output

For each test case, output Vibberish if the text is most likely in Vibberish or Cibberish if the text is most likely in Cibberish. If it is equally likely to be Vibberish or Cibberish, then output Gibberish.

Sample Input 1

asdfeji isfldkj sfdjkdflj wjiewjlf

Sample Output 1

Cibberish

Sample Input 2

aeiou dundundun

Sample Output 2

Gibberish

Sample Input 3

aeiou cool

Sample Output 3

Vibberish

Explanation of Sample Output 1

All four words have more consonants than vowels, so it’s likely Cibberish.

Explanation of Sample Output 2

One word has mostly vowels and one word has mostly consonants, so it’s Gibberish.

Explanation of Sample Output 3

There is one word with a vowel majority and no words with a consonant majority, so it’s likely Vibberish.
