        temp = []
        s = list(s)
        for i in s:
            if i in [‘a‘,‘e‘,‘i‘,‘o‘,‘u‘,‘A‘,‘E‘,‘I‘,‘O‘,‘U‘]:
                temp.append(i)
        temp.reverse()
        pos = 0
        for i in range(len(s)):
            if s[i] in [‘a‘,‘e‘,‘i‘,‘o‘,‘u‘,‘A‘,‘E‘,‘I‘,‘O‘,‘U‘]:
                s[i] = temp[pos]
                pos += 1
        return ‘‘.join(s)
