round up questions #114, 122

[Paul Bailey]

Q #114 is not very clear, it uses and example and then the answere don't pertain to that example, except the right one. Perhaps the correct answer should be (when you bit shift by more than the number of bits available your result is) the number bitshifted by the value you input for the bit shift modulo the total number of bits.
for #122, the expalnation starts with "An" and should start with "A".
