Question 1
Let f be a function from the set 𝐴 = {1,2,3,4} to 𝐵 = {𝑝, 𝑞, 𝑟, 𝑠} such that, 𝑓 = {(1, 𝑝)(2, 𝑝)(3, 𝑞)(4, 𝑠)}. Is 𝑓−1 a function?
Discuss “Distinguishability” of one string from another and explain how it affects the number of states in an FA. Considering the example of 𝐿 = {𝑎, 𝑏}∗{𝑎𝑏𝑎}, how do the distinguishable strings in L relate to the number of states in its FA?
