Please give me a code in c

dont change any written code

Thanks!!

Description: Given two arrays of non-negative integers, denoted as arrA and arrB. Please use the implemented ADT to complete the missing part of the following code: 1. create the setA and setB from the arrays arrA and arrB; 2. calculate the union of setA and setB, and print it out; 3. calculate the intersection of setA and setB, and print it out.

Input: Three lines, where: First line is two integers A and B; Second line is arrA of A non-negative integers; Third line is arrB of B non-negative integers; 0 <= A, B <= 10^3 Output: The first line is the union set The second line is the intersection set Sample Input 1: 2 3 5 6 7 5 8 Sample Output 1: 5 6 7 8 5 

Please whether it is correct
