Problem
1. The leftmost hit of a 4 x 3 S-box rotates the other three hits. If the leftmost bit is 0, the three other bits are rotated to the right one bit. if the leftmost hit is 1. the three other bits are rotated to the left one bit. If the input is 1011, what is the output? If the input is 0110, what is the output?
2. Write a routine an pseudo code that splits an n-bit word to two words, each of nf2 bits.
