Flip upper case with lower case

If we print the binary() form of ASCII letters: println(binary('A', 8), hex('A', 2), (byte) 'A'); // 01000001 41 65 println(binary('a', 8), hex('a', 2), (byte) 'a'); // 01100001 61 97 println(binary('Z', 8), hex('Z', 2), (byte) 'Z'); // 01011010 5A 90 println(binary('z', 8), hex('z', 2), (byte) 'z'); // 01111010 7A 122 exit(); We’re gonna notice the only diff. between an uppercase ASCII letter from its corresponding lowercase is that the 3rd bit of the latter is 1.
