1's complement :
It is obtained by changing all 1's to 0's and al 0's to 1's.

Example : 0110.
It's 1's complement is 1001.

Just change the 1 with 0 and 0 with 1.
1-->0
0-->1
So, 10-->01.

@Ashok.

In binary representation 5 is 101.

So, complementing the bits we have 010 i.e. 2.

In One's complement replace the opposite value in the given number.

To allow only 0 or 1 only.

If 0 means to replace 1 and 1 means to replace 0.

10 binary is 110.

So 1's complement is 001.

I initially think that it's 10 in number. It's a binary number so answer carefully .
