Consider a two round Feistel network with 8 bit blocks and 5 bit system key k = 10110. The key schedule generates the ith round key k, by deleting the ith bit of k using the indexing k =b1b2b3b4b5. The round key function fork) takes as input the pair of 4 bit strings 2 = 10243&4 and ky = 6,62b3b4 and produces as output the 4 bit string b2c3ba. Encrypt the number 7 whose ASCII code is 00110111
