Words with Two Vowels

Given a sentence, print every word that contains exactly 2 vowels.

Input

A single line of 1 to 10^5 characters containing a sentence with at least one word. Words contain only English letters (a-z, A-Z) and are separated by one or more spaces, and the line may start or end with spaces.

Output

The matching words, each on a separate line, in the order they appear. If no words match, print nothing. The vowels are a, e, i, o, u, uppercase or lowercase.

Examples

Input:  hello world apple
Output:
hello
apple

Input:  cat dog fly
Output:

None of these words has exactly 2 vowels (cat has 1, dog has 1, fly has 0), so nothing is printed at all, not even a blank line.

Input:  bee tree free
Output:
bee
tree
free

Every word can match. There's no rule saying only some words are allowed to.
