Appendix B Problem 3

Let Ω = {1,2,...,100} and let A,B and C be the following subsets of Ω.

A = {positive even numbers which are at most 100}
B = {two-digit numbers where the digit 5 appears}
C = {positive integer multiples of 3 which are at most 100}
D = {two-digit numbers such that the sum of the digits is 10}

List the elements of each of the following sets:

a) B\A
b) A∩B∩Cc

c) ((A\D)∪B)∩(C ∩D)

How to write a C++ program. Additive persistence is a property of the sum of the digits of an integer. The sum of the digits is found, and then the summation of digits is performed creating a new sum. This process repeats until a single integer digit is reached. Consider the following example: 1. The beginning integer is 1234 2. Sum its digits is 1+2+3+4 = 10 3. The integer is now 10 4. The sum of its digits is...
