Bitwise Inverter
write a program that performs a bitwise invertion to a given number
Examples:
invertbits(3) => returns 252 (11111100)
invertbits(255) => returns 0 (00000000)
global invertbits section .text ; <--- unsigned invertbits(const int num) ---> ; rdi=num invertbits: xor rax, rax ; EAX <- the result not rdi mov rax, rdi ret ; ---------> endof invertbits <---------unsigned char invertbits(unsigned char value){return value ^ 0xFF;}- global invertbits
