What is the minimum number of bits you need to encode a 26 letters of the alphabet plus a space?

The answer to this question would be 5 bit

One bit can be used to code either 0 or 1. That means every one bit there is two possibility. Two bit can contain 4 possible way to code, three bit will be 8. That will go as  where x is number of bit. In this case, there is 26 letter with space so there is a total of 27 possible code needed. Then you will at least need 5 bit which gives you [tex] 2^{5} or 32 possible way

Because without physical activity, the body has extra "energy" if you will, and so when it is time for bed you are not tired, so you end up staying up all night. also there is probably an effect on your internal clock, which messes with your melatonin production which goes hand in hand with your sleep cycle
