[swift]位元運算(Bitwise operator)

以底下兩數字為例：

let bin1:UInt8 = 0b11111111 //255
let bin2:UInt8 = 0b00001000 //8

let andResult = bin1 & bin2
print(String(andResult,radix: 2))//00001000

or運算

let orResult = bin1 | bin2
print(String(orResult,radix: 2))//11111111

xor運算

let xorResult = bin1 ^ bin2        
print(String(xorResult,radix: 2))//11110111

not運算

let notBin1Result = ~bin1
print(String(notBin1Result,radix: 2))//00000000
                
let notBin2Result = ~bin2
print(String(notBin2Result,radix: 2))//11110111

nor運算

let norResult = ~(bin1 | bin2)
print(String(norResult,radix: 2))//00000000
