[96, 90, 43, 94, 52, 82, 50, 31, 51, 58] Notes: • Your answer should be a single valid, non-negative, literal Python int value. For example, 123 is a valid int literal. • This question is asking about before any partition operation is carried out. • This is not asking for the median-of-3 index. • You can pre-check your answer (to check it's a valid, non-negative, literal int).

Create a Python dictionary that returns a list of values for each key. The key can be whatever type you want. Design the dictionary so that it could be useful for something meaningful to you. Create at least three different items in it. Invent the dictionary yourself. Do not copy the design or items from some other source. Next consider the invert_dict function from Section 11.5 of your textbook. # From Section 11.5 of: # Downey, A. (2015). Think Python: How to think like a computer scientist. Needham, Massachusetts: Green Tree Press. def invert_dict(d): inverse = dict() for key in d: val = d[key] if val not in inverse: inverse[val] = [key] else: inverse[val].append(key) return inverse Modify this function so that it can invert your dictionary. In particular, the function will need to turn each of the list items into separate keys in the inverted…To create a dictionary, you just surround a sequence of value pairs of separated by: and the pair separated by commas, within curly braces.
