Replacing 1 with 0 and 0 with 1 is a one's complement.
Eg;

@Gopal.
For 2's complement, we first find 1's complement and then add 1 in that number.
Eg:
We have a binary number 0111,
2's complement = [1's complememt] + 1 .
1's complement = 1000,
now add 1,
1000
+ 1
===========
1001

10 in binary form is -1010.
its 1's complement will be -0101.
Then how the answer is -01?
its 1's complement will be -0101.
Then how the answer is -01?

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

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.

9's Complement of 234.
999 - 234 = 765.
And 9's Complement of 1423.
9999 - 1423 = 8576.
999 - 234 = 765.
And 9's Complement of 1423.
9999 - 1423 = 8576.
