1 bit must be flipped because:
A=01000001
a=01100001
So to go from a to A you have to change the 3rd bit from 1 to a 0.

Only one ... the third bit of the byte, numerical 32. Every lower-case letter
has a '1' in that place. If that bit is changed to '0', then the code represents
the upper-case form of the same letter.
