Eg:- 1101001
2's Compl:0010111
Answer #2The above stated method fails for 11000. Otherwise we can use a method which is when the last bit is 0 check the next bit towards the left, if it is a 0 again then check the preceding bit, if it is 1 keep aside the bits after this one and the one itself and invert the rest of the bits.
