In c#

Design and implement two classes, each of which encapsulate distinct closePrime objects. - The first type, sameLastDigit, uses 2 closePrime objects to identify all pinged values that yield stepped primes with the same last digit. For example, if a trigger object encapsulated closePrime objects with hidden digits 2 and 5 then a pinged value of 81 would satisfy this criterion (2 steps away: 83, 89 => 97; 5 steps away: 83, 89, 97, 101, 103 => 107) while a pinged value of 78 would not. Cumulative statistics may also be released.
