Define a recursive function named immutify; it is passed any data structure that contains int, str, tuple, list, set, frozenset, and dict values (including nested versions of any of these data structures as an argument). It returns an immutable equivalent data structure (one that could be used for values in a set or keys in a dict). The types int, str, and frozenset are already immutable. Convert a set to a frozenset; convert all the values in a tuple to be their immutable equivalents, in the same order); convert a list to a tuple (with immutable equivalents of its values, in the same order); convert a dict to tuple of 2-tuples (see the association tuple in question 2) but here with the 2-tuples sorted by the dict’s keys. If immutify ever encounters a value of another type (e. g., float) it should raise a TypeError exception.

The following call (with many mutable data structures)
Example 1:
immutify( {'b' : [1,2], 'a' : {'ab': {1,2}, 'aa' : (1,2)}} )
returns the immutable data structure
(('a', (('aa', (1, 2)), ('ab', frozenset({1, 2}, ('b', (1, 2)))
Example 2:
immutify( [{1,2}, {3,frozenset([4,5])}, {6,7}])
Returns
(frozenset({1, 2}), frozenset({3, frozenset({4, 5})}), frozenset({6, 7}))

A.) generate scaffolding to create database for your application. develop all the entities identified in assignment #2. add any additional that may be identified later. b.) add data validation rules to the models that are appropriate for your application and data. c.) create links for each scaffold in the header section. part 2: application updates [30 points] a.) add two additional views to the "home" controller you created in assignment #1. b.) the two views should be named as “privacy" and "". c.) link the two newly created views in the footer section. hint: you would need to modify the “home" controller definition and create “privacy.html.erb" and “.html.erb" files in appropriate locations.

[a] create a class called “cycle” which has two instance integer variables as properties, “numberofwheels” and “weight.” create a constructor with two parameters, using the same variable names in the parameter list. assign each variable to numberofwheels” and “weight” respectively. write a separate application to test the class and display its properties. note: do not change the names of the instance variables or the variables listed in the constructor’s parameter list. [b] edit your class cycle by adding a default constructor which will assign the default values of 100 to represent the numberofwheels, and 1000 to represent the weight, by invoking a call to the other constructor. modify your application created in [a] to test the class.
