. A case-insensitive permutation of the Latin alphabet A = {A, B, C, ..., Z, a, b, c, ..., Z} is a one-to-one map 4: A+ A such that uppercase is mapped to uppercase; lowercase is mapped to lowercase; and S(A) is the uppercase of y(a), 4(B) is the uppercase of 4(b), and so on. Under a case-insensitive permutation 4 of the Latin alphabet, the sentence . "It is effort, kindness, passion, and zeal that are beautiful, charming, excellent, as well as quirky, not jealousy and vulgarity." is converted to the sentence Ty tk joocwy, ftuvujkk, dikktcu, iuv hjig yliy iwj njiqytoqg, zliwxtus, jmzjggjuy, ik bjgg ik eqtwfa, ucy pjigcqka iuv rqgsiwtya. (a) Write a C++ program to determine the permutation 4. The program should display the value of the permutation at each letter as follows, where (a) = i, 4(6) = n, 4(e) = 2
