Question

How many bits must be “flipped” (i.e., changed from 0 to 1 or from 1 to 0) in order to capitalize a lowercase ‘a’ that’s represented in ASCII?

Answer 1

bin(ord('A')) = 1000001
bin(ord('a')) = 1100001
looks like you just flip the one bit. a xor 1000000 = A

Answer 2

ASCII A =65
ASCII a =97

difference is 32: One bit O%40
