1. Develop software specifications for a simple e-shopping system using the formalism of finite state machines. Consider some selected functionality. Make appropriate assumptions.
Note: there could be a variety of possible solutions; there is nothing wrong about that. Your answer will be evaluated on a basis of its completeness and correctness (taking into consideration the assumptions you have made).

2.Suggest a collection of test cases to test a procedure finding a maximum of three integer
numbers
maxofThreeNumbers(int n1, int n2, int n3)
Consider (i) exhaustive testing and (ii) error guessing.
3.(i) Suppose that an application has n inputs (variables) and each variable partitions its input space in m equivalence classes. Determine the number of equivalence classes. How many tests do you require. Could be the number of tests made lower? Do detailed calculations for n =10 and m =10.
(ii) a system invokes function S if the reading of a given sensor is within the [a, b] or [c, d], b
