Using SDES, decrypt the string 10100010 using the key 0111111101 by hand. Show intermdiate results after each function (IP, FK, SW, FK, IP-1). Then decode the first 4 bits of the plaintext to a letter and the second 4 bits of the plaintext to another letter where we encode A through P in base 2 (i.e., A=0000, B = 0001, ..., P= 1111). (Hint: As a midway check, after the application of SW, the string should be 00010011
