Question 3. Let us consider the f-Function (Fig. 3.8, sec. 3.3.2) used in the DES algorithm. Suppose input to this function is the 32-bit input expressed in hexadecimal as 12ABCDEF, determine the 32-bit output of the function expressed in hexadecimal representation. The 48-bit key to the function is 1A2B3C4D5E6F in hexadecimal.
