$1.$ Consider the following procedure and answer these questions:

a$)$ Suppose that if $($ x $<$ y $)$ line is mutated to if $($ x $<=$ y $).$ Generate a test case that will

distinguish this mutant.

b$)$ Suppose that if $($ x $<$ y $)$ line is mutated to if $($ x $<$ y $+1).$ Generate a test case that

will distinguish this mutant.

c$)$ Suppose that return x $*$ y; line is mutated to return x $/$ y;$.$ Generate a test case that will

distinguish this mutant.
