Write a pure function cycle-streams that takes streams, xs and ys, and returns a stream. The streams may or may not be the same length, and either one may be infinite, but you may assume they are both non-empty. The elements produced by the stream are pairs where the first part is from xs and the second part is from ys. The stream returned by cycle-streams cycles forever through the streams xs and ys. A constant-time ( O ( 1 ) O(1)) solution is possible.

Assume the existence of a bankaccount class. define a derived class, savingsaccount that contains two instance variables: the first a double, named interestrate, and the second an integer named interesttype. the value of the interesttype variable can be 1 for simple interest and 2 for compound interest. there is also a constructor that accepts two parameters: a double that is used to initialize the interestrate variable, and a string that you may assume will contain either "simple", or "compound", and which should be used to initialize the interesttype variable appropriately. there should also be a pair of functions getinterestrate and getinteresttype that return the values of the corresponding data members (as double and int respectively).
