Vowel Cover X34889
We say that a string s is covered by vowels (it’s vowel_covered) if s is longer than 4, its initial and final positions are uppercase vowels and its second and last but one positions are lowercase vowels. Thus AiaI is not covered by vowels since its length is 4, but AureA is covered by vowels.
Implement the function is_vowel_covered(s) which returns True if a given string s is vowel covered and False otherwise.
