5. Write a Python function remove_equal_to(), which takes a dictionary d in the format of {int: int, ..., int:int} as input (note that the length of the dictionary is not fixed, and it can contain any number of entries), and removes from that dictionary all the entries whose keys are equal to at least one of the values associated with the other keys in d, and returns the number of entries that were removed. (10 Points) Hint: The following table indicates what are the expected outcomes after calling the function remove_equal_to() on some test cases. Example Dictionary before function call Dictionary after Retur Description n function call Value Empty {} 8 0 dictionary Single entry {1:2} {1:2} 0 dictionary Multiple entries, {1:5, 5:6} {1:5} 1 one removal Multiple entries, {1:5, 2:6} {1:5, 2:6} 0 no removals Multiple entries, {1:5, 5:6, 6:2} {1:5} 2 multiple removals
