addition for question 2
Complete the implementation of the Set class given in Listing 4.1 on page 114 in your textbook by providing implementations for the following methods, some of which have been provided to you in your textbook already: . . union( self, other_set ) : returns the union of this set with the other_set intersection( self, other_set ) : return the intersection of this set and the other_set difference self, other_set ) : returns a set of of elements that are in the current set but not in the other_set symmetric_difference( self, other set ) : returns the symmetric difference between this set and the other_set O Demonstrate that this Set class implementation works as specified. [1] : # Provide your implementation here. # # Use as many code cells as you wish # # Preferably use separate code cells for class code and test code # Question 2 Consider Table 4.5 on numbered page 112 in your textbook. Write the Python functions described below: amortized_cost( i ) returns the costs si, ei, and size values for a given i value, where i 21. generate_table( n ) should print out a table such as Table 4.5 for any given n. For example, Table 4.5 would be for n= 16, the number of items to be appended to a list. . 112 CHAPTER 4 Algorithun Analysis 4 in - - Size List Contents Dparnis, he 1 1 1 pererte Da manirim naria di LPT www.will Il/LIVE 2 1 1 12 15 expansion Corti_syu can tellim IT.
