In this lecture, we will address the problem of representing sets using C#. Sets are collections of elements that do not allow duplicates, and they are useful in certain situations. For example, sets can be effectively used when handling lists of unique user IDs or various product codes.<\/p>\n
Given two arrays To solve this problem, it’s essential to understand the definitions of each set operation and how to utilize sets in C#.<\/p>\n In C#, sets can be easily implemented using the Now we will implement the required function Let\u2019s explain the above code step by step.<\/p>\n First, we create a To calculate the union, we first make a copy of The intersection is obtained by calling the The difference is calculated by removing elements of Finally, the full code that includes all content is as follows:<\/p>\nA<\/code> and B<\/code>, implement a function that calculates the union, intersection, and difference of the two arrays. The function is defined in the following format:<\/p>\npublic static void CalculateSets(int[] A, int[] B)<\/code><\/pre>\n2. Solution Process<\/h2>\n

2.2 C# Set Class<\/h3>\n
HashSet<\/code> class. A HashSet<\/code> does not allow duplicates and can represent an unordered set.<\/p>\n2.3 Function Implementation<\/h3>\n
