SOLVED: Write a C program using the fork() system call to create a child process that executes Kaprekar's Operation for a 3-digit number. The child process is required to print out the intermediate result as shown below. The input number should be provided from the command line. You can use the number "123" as the testing input.Given the number 123, the Kaprekar's process is:321 - 123 = 198891 - 198 = 693963 - 369 = 594954 - 459 = 495954 - 459 = 495The output should look something like this:Chil
