Is this possible??? to implement this logic?

[sufi52]

Write a function which should add the two vowels in the arrays and generate third array and store vowels only once if repeated, if is mandatory that there should be no occurrence of any character from a-d in any array.

I'have tried more every way i understand but unable to implement anyone else??

What actually have you tried?
What was your plan?
What didn't work?

1: What does "add the two vowels" mean?
2: Discard duplicates.
3: Create a third(?) array.
4: Store in this third array unique vowels and all consonants except {a b c d}

Assuming character array(s)? then the issue is compare two arrays(?) one character at a time. Store one instance of a duplicated vowel(?) in the third array and all consonant which are not in the range a - d.

Do you have code samples of what you've tried?
