Consonant – Vowel Pairs

The program must accept a string S as the input. The program must print all the pairs having a consonant followed by a vowel in the string S (in the order of occurrence) as the output.

Note: The string S always contains at least one pair having a consonant followed by a vowel.

Boundary Condition(s):
2 <= Length of S <= 100

Input Format:
The first line contains the string S.

Output Format:
The first line contains all the pairs having a consonant followed by a vowel separated by a space.

Example Input/Output 1:
Input:
volcano
Output:
vo ca no
Explanation:
The string “volcano” contains three pairs having a consonant followed by a vowel. So the pairs vo ca and no are printed as the output.

Example Input/Output 2:
Input:
TELEVISION
Output:
TE LE VI SI
