For the following three questions, remember that bit numbers start numbering from 0 at the LSB (least significant bit). Assume that these hexadecimal numbers are always unsigned. In addition to showing the mask you would use, also show the operation you would use, like so: &0x0020. (i.e., AND the original number with the hexadecimal mask 0x0020.) a) You want to take any 4-digit hexadecimal number and only show bit 14 (remember you start counting at 0 ) by doing a logic AND operation on it with a "mask". Specify what that mask needs to be and express it as a 4-digit hexadecimal number (i.e. in the form of 0xhhhh ). Briefly explain your answer. b) Specify the mask you would need to change just bit 14 of any given number to zero. That is, the result of this operation gives you a new number, which is the given number but with that bit 14 equal to 0 . Again, all these numbers are 4-digit hexadecimals, so express your answer as such. Briefly explain your answer. C) Similarly to the previous question, specify the mask you would need to set bit 14 of the unknown number to one. Express it as a 4-digit hexadecimal number. Briefly explain your
