If you are given a word of size n bits, the range of 2’s complement

1.	If you are given a word of size n bits, the range of 2’s complement of binary numbers is ________(a) -2^n+1 to +2^n+1(b) -2^n-1 to +2^n-1(c) -2^n-1 to +2^n+1(d) -2^n-1 to +2^n-1-1This question was addressed to me by my college director while I was bunking the class.My question comes from Sign Magnitude in chapter Computer Arithmetic of Computer Fundamentals
Answer» Right choice is (d) -2^n-1 to +2^n-1-1 To explain I WOULD SAY: 2’s complement is obtained by adding 1 to the 1’s complement. For e.g. 5 :0101 and 1’s complement=1010and2’s complement=1011.
