if i have two positive integers, say 0x1234 and 0x5678, is 0x8765 + 0xfedc = 0x8641, if the '+' means two's complement addition, mod 2^16?

I've decided to do it this way
flip numbers 0=1, 1=0
add 1 to LSB
if carry, loop until array[i]==0
But I'm stuck on the last point; how can I say that in a conditional loop?

I got a bit stuck with my algorithm and I need some help to solve my problem. I think an example would explain better my problem.
Assuming:
d = 4 (maximum number of allowed bits in a number, 2^4-1=15).
m_max = 1 (maximum number of allowed bits mismatches).
kappa = (maximum number of elements…

i know unsigned,two's complement, ones' complement and sign magnitude, and the difference between these, but what i'm curious about is:
why it's called two's(or ones') complement, so is there a more generalize N's complement?
in which way did these genius deduce such a natural way to represent negative…

That's x \ y using mathematical notation. Suppose
x <- c(0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,2,1,1,1,3)
y <- c(0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,1)
How can I get a vector with ALL the values in x that are not in y. i.e the result should be:
2,1,1,3
There is a similar question here…
