3. Implement q3(inputString, minLetter, lettersTolgnore, specialLetter) so that it returns three things: the smallest letter in inputString that is both greater than minLetter and not in lettersTolgnore, or None if no such letter exists the highest index at which that smallest letter occurs, or None if such a letter does not exist True if specialLetter occurs an odd number of times in inputString, False

Python Help me please

3. Implement q3(inputString, minLetter, lettersTolIgnore, specialLetter) so that it returns three things: the smallest letter in inputString that is both greater than minLetter and not in lettersTolgnore, or None if no such letter exists the highest index at which that smallest letter occurs, or None if such a letter does not exist True if specialLetter occurs an odd number of times in inputString, False otherwise inputString is a string a zero or more lower case letters, minLetter is a lower case letter, lettersTolgnore is a string of zero or more lower case letters, and special letter is a lower case letter NOT in lettersTolgnore. Use a simple while loop. You may not use any string methods (such as .count()), but you may use the 'in' or 'not in' operators. E.g. >>> q3("bссacbd", "a", "eb", "z") ('c', 4, False) >>> q3 ("bccacbd", "a", "aefg", "d") ('b', 5, True) >>> q3 ("abc", "d", (None, None, True) >>> q3 ("aaabac", "d", "", "a") (None, None, False) ", "a") Remember, as in HW1, to return three values, simply list them in the return statement with a comma separating each. E.g. return (smallestLetter, indexOfSmallestLetter, speciallsOddlyThere) or return smallestLetter, indexOfSmallestLetter, specialIsOddlyThere
