Vocals to Morse translator X66038

Statement

We want to translate into Morse code message written using only capital vowels that is hidden in a string $s$ .

For example, if $s$ = “LALALAlalala” the message is “AAA” and its translation to Morse code is “.- .- .-”.

Implement the function @morse_vowel_translator (dic_morse_vow, s)@ such that given the dictionary @dic_morse_vow@ whose keys are the capital vowels and their values their respective Morse codes, returns the translation of the message hidden at $s$ . To find this message, you have to extract from $s$ the capital vowels that it contains, preserving the order in which they appear. The translation of the message is simply the Morse code of each capital vowel, separated by a blank space. In case the message is empty, an empty string must be returned.

Observation

The dictionary @dic_morse_vow @ = “A”:“.-”,“E”:“.”,“I”:“..”,“O”:“---”,“U”:“..-” will be given in private test cases.
